Fixes #9130

This fixes a regression introduced in 0.13.0, where websites hosted via
index.html placed in UnixFS directory were always returned with
Cache-Control: public, max-age=29030400, immutable
even when loaded from mutable /ipns/ contentPath.

This adds a missing test for #3963

This fixes a regression around directory listing and index.html hosting.
Seems that during one of recent refactors code changed and we no longer
check for trailing slash in HTTP request path, but look at content path
instead.

This cleans this up and also ensures dir behavior is the same for
both index.html hosting and dir-index-html (generated listing).

It also adds more tests so we catch any future regressions.

fix(gw): directory URL normalization

Copied npm/choco/snap context from #9095

feat: go-libp2p v0.21 (rcmgr auto scaling)

See the release notes: https://github.com/gabriel-vasile/mimetype/releases/tag/v1.4.1

This is a valuable release with already public security fixes (which don't affect us AFAIT but better safe than sorry).
More mimetypes and bug fixes.

feat: make corehttp a reusable component

This cleans up old CORS tests and adds more resolution
(proper Origin test, testing custom header behavior)

It also adds basic regression tests for /api/v0
subset exposed on Gateway port.

Better 'ipfs add --help'  docs, based on feedback from
