fix: escape names that might collide with other operations

[laurentsenta]

Fixes the log rendering issue we've seen in bifrost

https://github.com/singulargarden/bifrost-gateway/actions/runs/6157325821/job/16707825616

Calling t.Run("this is a test for /ipfs/something", ...) will create outputs names like:

• TestRoot/TestParent/this_is_a_test_for/ipfs/something/Body

Which breaks the test generations and creates a weird structure when rendering the tests.

• Use HTML encoding to escape these names.
• check the output and maybe un-encode

Examples:

• https://singulargarden.github.io/gateway-conformance/results/bifrost-gateway/main/test-gateway-cache
• https://singulargarden.github.io/gateway-conformance/tests/test-gateway-cache/get-for-ipfs-with-only-if-cached-succeeds-when-in-local-datastore/status-code/
