The action hardcodes https://github.com/mozilla/sccache/releases/download/... as the download origin. Air-gapped or egress-restricted runners can't reach GitHub.

Add an input (e.g. download-base-url) so operators can point at an internal mirror that serves the tarball and the .sha256 sidecar with the same filenames. Keep checksum verification on against the mirrored sidecar.

Tracked in SECURITY.md under "What is not done yet".
