ccache should not create caches for PRs

[TimWolla]

Description

Currently the ccache integration for GitHub Actions also creates caches for PRs, needlessly wasting cache space. It should likely be configured to only ever restore caches, but not create a new one:

It would still benefit from any caching done for the master branch, but not create any redundant branch-specific cache.

We can probably use the save option for this.

Yes, I also linked that 😄 I’ll have a look at fixing this in the next days. I primarily filed this issue to keep track of it, as I couldn't immediately get around to creating and testing a PR.

Ah, sorry 😄
