Fix incorrect cache-dependency-glob in CI

[deining]

With the lastet CI + CD run, a warning is shown:

Build docs
No file matched to [/home/runner/work/pls/pls/examples/examples/uv.lock].
The cache will never get invalidated.
Make sure you have checked out the target repository and configured the cache-dependency-glob input correctly.

This PR fixes this issue.

Good catch, the working-directory (added in 9ffbf56) combined with cache-dependency-glob to create double nesting.
