Daz DeBoer 0a36ca9fb8 Use 'cache-read-only' for all but default_branch ...

Cache entries _written_ from jobs run on a non-default branch will be private
to other jobs for that branch. When development flow involves working on a
feature branch and then merging into 'main', these branch-private cache
entries can result in eviction of other (shared) cache entries generated
for the default branch.

With this change, we make the recommended setup the default, by running
with `cache-read-only: true` for any jobs run on a non-default branch.
These jobs will be able to read cache entries written from the main branch,
but will not write any cache entries.

Fixes #143
