Update action versions and fix build-and-test step in update-codeql workflow (#158)

* Update actions versions to latest

Updates the commit reference for the `softprops/action-gh-release`
action to point to the latest released version.

Fixes an outdated "actions/checkout" version reference in an
agent skill definition, for consistency.

* Fix build-and-test in update-codeql.yml workflow

This commit is an attempt to fix the "build-and-test" step
of the update-codeql.yml actions workflow, which has been
failing due to missing dev/test dependencies on "ubuntu-latest"
actions runner:

- New step "Update - Install xvfb and VS Code dependencies" - Installs
  xvfb (virtual framebuffer) and system libraries VS Code needs
  (matching the pattern from copilot-setup-steps.yml).
- Wrapped npm run build-and-test with xvfb-run -a to provide a virtual
  display — matching how build-and-test-extension.yml runs integration
  tests.
