Merge pull request juju#17645 from barrettj12/update-gh-actions

juju#17645

Our GitHub checks are producing lots of warnings, due to the deprecation of Node 16 in GitHub Actions: 
https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/
https://github.blog/changelog/2024-03-07-github-actions-all-actions-will-run-on-node20-instead-of-node16-by-default/

Update dependent actions to newer versions which use Node 20. Specifically, I have updated the following actions:
- actions/checkout: v3 -> v4
- actions/setup-go: v4 -> v5
- dorny/paths-filter: v2 -> v3

The `balchua/microk8s-actions` action can't yet be updated, as they have not yet released a new version with Node 20. Same with `canonical/has-signed-canonical-cla`.
