Fix confluence export

[zmully]

An attempt at fixing some of the problems with the psp builder Confluence exporter:

1. The existing relative link processing replaces all links on a page with the first link it finds. This is most obvious on the index.md page which links to all other pages.
2. The existing relative link processing stripped all links of any relative page anchor ids (i.e data-mgmt.md#data-classification-model was stripped to just data-mgmt.md) because of the existing broken regex.
3. There was a hack around GFM indentation for lists, but it only handled lists with one sublevel. Enabling the showdown option disableForced4SpacesIndentedSublists: true instead is preferable.

Problems I tried to fix, but couldn't:

1. The template anchor ids, like [Data Classification Model](data-mgmt.md#data-classification-model) don't work in Confluence, as Confluence doesn't support them on import (? I'm not actually sure what is happening). Confluence instead generates it's own case-sensitive ids, #Data-Classification-Model, so deep linking doesn't work.
2. The base templates do not follow a standard capitalization anchor id format, there are some Pascal-ish kebab (Lorem-Ipsum-Lorem), and some straight kebab (lorem-ipsum-lorem). I prefer the templates adhere to and enforce straight kebab if the Confluence import issues can be handled, so I don't have to bother with the correct captialization of the anchor ids.

Finally got some time to add support for exporting policies under a parent page and added some debugging since the export goes through a couple of intermediary steps that make it difficult to diagnose format issues in Confluence without.

There were no preexisting tests for any of the confluence code, so I didn't go there either with this PR. Additionally, I did not try to diagnose the test failures with existing code that I did not modify as it is unclear if those were related to my local setup, or if they've been broken for while.

Looks good, merging into a test branch to test locally before merging into main

The base branch was changed.

The debug flag isn't being parsed out of the options, and the publish to confluence function doesn't seem to find the correct files to publish. I won't be merging this into the main branch for now.

@behobu can you please be more specific? I think this might have sat so long that you've since switched CI systems, and I can't see the results from around the time of your comment.

👋 Sorry to do this, but I'd love to get some attention from J1 staff on this PR. It looks like behobu may no longer be an employee of J1, so I'm unfortunately going to spam active J1 people for attention.

Anyone? Anyone? Bueller? Bueller?

Additionally, in this last commit, I fix the broken revision logic. It looks like you had some copy pasta to provide a defaultRevision if none were specified, but one overwrote the config.json value and the other didn't. I've removed the duplicate function and fixed the logic for the revision.

Hey @zmully 👋 Thanks for the PR! @behobu is still at J1. He should be able to review the PR.

One thing, do you mind backing out the changes to yarn.lock. We typically update dependencies internally for security reasons.

Hello @zmully. I just checked in on the status of getting this reviewed and merged. It hasn't been forgotten, but the expectation is that it may take a bit of time to validate fully, so it's on the list but not at the top. Thank you for your contribution and patience!

@aiwilliams we're coming up on a year and change, and I'm having to use my own branch again to publish my policy docs internally to our wiki. I can't imagine I'm the only one who is stuck publishing their policies to Confluence, and I'd appreciate it if either you all could review this PR, or if you've no interest the PR, then please let me know, so I can close it, and maintain my own patched version of the tool.
