[Release] Missing Alpine codecovcli binary releases integrity check signatures #703

Previously, Alpine codecovcli binaries were distributed at cli.codecov.io/${CODECOV_CLI_VERSION}/alpine/ along with the checksums and signatures.
However, the directory structure of cli.codecov.io has changed recently, and the Alpine binaries aren't uploaded since v11.

Alpine codecovcli binaries are still available as GitHub Release assets, but there are no checksums or signatures. (Only signatures for sentry-prevent-cli are uploaded.)

Please consider making integrity-check signatures for Alpine codecovcli binary releases available again.
