ci: Migrate to paths-filter

The technote-space/get-diff-action repo is no longer maintained and
archived. Last commit was 2 years ago.
On the other hand dorny/paths-filter is actively maintained, last commit
was 6 months ago and has far more stars 2100 vs 190 for get-diff-action.
Last but not least paths-filter would better handle push force scenario.

Also bump actions versions to keep the CI up to date.
