Pin ccache-action to a version that updates the PATH

[kendalharland]

See hendrikmuhs/ccache-action#204. This is necessary for this workflow to run on custom runners where $USERPROFILE/.cargo/bin/ or any future installation path isn't already part of $GITHUB_PATH

I think that we should wait a bit and see if upstream responds. IIRC, they were pretty responsive, so giving them 24-48h seems reasonable.

I think this is reasonable. At the same time, waiting for upstream reviews from someone I can't directly contact, who also has their own priorities outside the project creates an undesirable slow down :/ I wonder if there is a less distributed strategy for managing changes to the 3p actions we depend on, such as keeping our own forks that are auto-synced, and retroactively upstreaming all changes when possible.

@compnerd let's merge! Seems like upstream is not attending the PR at the moment. You'll have to do it since I don't have permission

[kendalharland]

Upstream has merged the change and this is no longer needed. I'll send a separate PR to revert back to hendrikmuhs/ccache-action
