deps: Switch docz-plugin-css implementation

[matheusd]

The current version of docz-plugin-css uses node-sass v4, which is
incompatible to node v16+.

Given that pi-ui does not use any sass files, this commit switches the
docz-plugin-css dependency to a forked version which drops node-sass and
is thus compatible to node v16+.

[matheusd]

When testing, please double check the docz: scripts are also running successfully.

Thanks for the PR!

I'm getting the following error when running yarn docz:dev in this PR with a fresh install of dependencies:

TypeError: One and only one of the "port", "server", or "noServer" options must be specified

Steps to repro:

rm -rf yarn.lock && rm -rf node_modules && yarn cache clean
yarn
yarn docz:dev

The command docz:build works as expected.

Looking at your PR I can't figure out why this happened.
I'm really considering ditching docz and going for another option to write pi-ui's docs. Docz has been a pain to maintain. What do you think?

[matheusd]

By that criteria (removing yarn.lock and rebuilding the dependency tree) it seems the current master is also broken.

Took me a bit, but I've been able to create resolution rules so that removing yarn.lock, then recreating it would yield a working docz:dev install. It really seems this version of docz isn't being maintained anymore, so at the very least, pi-ui should be upgraded to docz 2 if at all possible.

In any case, that's a much larger change then simply dropping sass support as I've done in this fork. Btw, I've updated the plugin-css fork to update the requirement to docz v1.2, so this also removes all dependencies to docz v0.

Had to add a new commit, adding --network-concurrency 1 to the CI scripts due to intermittent errors.

Weird. We've never faced issues with docz:dev on master.

Yes, but docz v2 isn't that stable either. That's why I'll be writing the docs using another generator: #361 (comment)

This PR is important because it allows us to use node v16+ on politeiagui and decredtion right now. I tested locally with the following node versions and works fine:

v12.22.10
v14.19.0
v16.14.0

The only issue is that I'm seeing a lot of warnings I wasn't seeing before. Adding the following plugins to babel.config.js cleared the majority of them:

plugins: [
    ["@babel/plugin-proposal-class-properties", { "loose": true }],
    ["@babel/plugin-proposal-private-methods", { "loose": true }],
    ["@babel/plugin-proposal-private-property-in-object", { "loose": true }]
  ]

Can you add these plugins to this PR?

Tested @tiagoalvesdulce solution and it works. It still displays some warnings, but I was able to run it. Good to mention that warnings are only displayed on first docz:dev run.

I am merging this and will open a new PR to add:

plugins: [
    ["@babel/plugin-proposal-class-properties", { "loose": true }],
    ["@babel/plugin-proposal-private-methods", { "loose": true }],
    ["@babel/plugin-proposal-private-property-in-object", { "loose": true }]
  ]
