feat: easier testing of a specific specification/IPIP

[SgtPooki]

Overview

Some of our tests mention/link to a specification, e.g.

gateway-conformance/tests/path_gateway_tar_test.go

Line 79 in e782d03

Spec: "https://specs.ipfs.tech/http-gateways/path-gateway/#content-disposition-response-header",

, but not all of them.

Goal

We should make it easier for folks who are reading specs, to run conformance tests for that specific test, and potentialy even target specific sections of those specs.

Examples

Trying to test https://specs.ipfs.tech/http-gateways/trustless-gateway could be as easy as:

gateway-conformance test <...> --specs http-gateways/trustless-gateway

You could target a subsection of that test (i.e. https://specs.ipfs.tech/http-gateways/trustless-gateway/#dag-scope-request-query-parameter) with something like:

gateway-conformance test <...> --specs http-gateways/trustless-gateway/dag-scope-request-query-parameter

Concerns and other thoughts

Tight coupling these like this will cause some pain, but it will also keep our specifications and conformance tests accurate and up to date.

Similar to #86, but for keeping conformance tests closer to specifications.
