Subject: [PATCH] Compare case-insenitively for full cache key match

Some self-hosted (or otherwise non-github-hosted) runners are
non-case-preserving for cache keys. To support such configurations, set the
`cache-hit` output variable to `true` if the found cache key matches
case-insenitively.

Fixes: https://github.com/Swatinem/rust-cache/issues/302
