feat: finish porting and cleaning all simple tests

[laurentsenta]

Closes #26

• t0109 - redirects
• t0112 - cors
• t0113
• t0114
• t0115 - dir listing
• t0122 - tar
• t0123 - dag
• t0117 - blocks
• t0118 - forked pretty heavily during feat: tests for IPIP-402 CAR parameters  #56
• t0124 - ipns

Notes

• I am reviewing all the tests and removing shell comments, which will mark the end of "porting sharness tests".
• Sister PR in Kubo: I reviewed every tests and removed the code that was duplicated. We don't migrate kubo-specific code, like testing /api/, behavior with configs, etc.

Nice job! I think we should also prepare an accompanying PR to kubo that removes ported tests from sharness there. (ipfs/kubo#9999)

Thank you @laurentsenta for driving this over the finish line ❤️

I did a pass over this and dropped some questions/comments/nits to address, but other than that lgtm.

As for Kubo PR, it is bit more tricky, left a review there, butI don't think that PR should block this one.

"dag" name is confusing because unixfs is a DAG too.

These are CBOR and JSON tests, and dag- variants are part of the story.
Maybe rename fixtures/path_gateway_dag→ fixtures/path_gateway_cbor_json for clarity?

Related to my other comments about naming and specs (#92 (comment)) I'd keep this in a different PR if that's OK with you

nit _dag_ in filename is confusing – CARs and UnixFS also have DAGs.
These are CBOR and JSON tests, and dag- variants are only part of the story.

Maybe rename tests/path_gateway_dag_test.go→ tests/path_gateway_cbor_json_test.go for clarity?

[laurentsenta]

We aligned these file names with the spec changes in #79

Spec defs:

gateway-conformance/tooling/specs/specs.go

Line 115 in de3b04b

PathGatewayDAG = Leaf{"path-dag-gateway", stable}

I'm worried if we change that filename here, we'll create inconsistencies with the rest of the code, I created #100 to capture your comments.

I think this one is mostly fine, as long as @lidel's comments are addressed. Same in Kubo land: ipfs/kubo#9999 - I think they can merged independently and I would like them to be merged as soon as possible to avoid future conflicts.
