helm/chart-releaser-action is now allowlisted upstream (ASF Actions
allowlist, apache/infrastructure-actions/actions.yml) at v1.7.0
(cae68fefc6b5f367a0275617c9f83181ba54714f), so the git-submodule fork
under .github/actions/chart-releaser-action — added as a workaround
when it wasn't allowlisted — is no longer needed. Verified with a
real CI run (install_only, no release side effects) before landing
this.
Also drops the now-dead debug step that cat'd the vendored action's
action.yml.
helm/chart-testing-action stays vendored for now: it's allowlisted at
v2.8.0 (6ec842c01de15ebb84c8627d2744a0c2f2755c9f), but that release
depends internally on astral-sh/setup-uv@v7.0.0, which isn't itself on
the allowlist (only v8.1.0+ are). De-vendoring it needs an INFRA
request to add that setup-uv SHA first — confirmed by testing it
directly, not just reading the config.
