ci: checkout tags for release builds (#7202)

In the Rust code, we use `git describe` to determine the current version
of the code. This only works if tags are actually checked out. To save
time, the `actions/checkout` action by default only does a shallow-clone
of depth 1 without any tags. Due to that, all events in Sentry just show
up as a commit hash.
