We temporarily can't build sccache on windows runners, but it's still available on linux.
this smol change lets us use it when available, instead of disabling across the board.
The Windows runners now have a conditional check to disable (unset the `rustc-wrapper` env var) sccache in their entrypoint, just like the Linux ones have.
Also the workflows no longer fail when `sccache --show-stats` fails.
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/3656
## Proposed Changes
* Replace `set-output` by `$GITHUB_OUTPUT` usage
* Avoid rate-limits when installing `protoc` by making authenticated requests (continuation of https://github.com/sigp/lighthouse/pull/3621)
* Upgrade all Ubuntu 18.04 usage to 22.04 (18.04 is end of life)
* Upgrade macOS-latest to explicit macOS-12 to silence warning
* Use `actions/checkout@v3` and `actions/cache@v3` to avoid deprecated NodeJS v12
## Additional Info
Can't silence the NodeJS warnings entirely due to https://github.com/sigp/lighthouse/issues/3705. Can fix that in future.
## Issue Addressed
I think we're running into this in our linkcheck, so I'm going to frist verify linkcheck fails on the current version, and then try downgrading it to see if it passes https://github.com/chronotope/chrono/issues/755
