fix: address CodeRabbit review — add pre_uninstall and ErrorAction

- qt-creator-cdb-ext-git.json: add -ErrorAction SilentlyContinue to
  post_install Remove-Item to suppress spurious error on fresh install
  when no prior qtcreatorcdbext* items exist
- qt-creator-cdb-ext-git.json: add pre_uninstall to remove junctions
  from qt-creator-git's lib before uninstall, preventing dangling
  junction references
- qt-creator-wininterrupt-git.json: add pre_uninstall to remove hard
  links from qt-creator-git's bin before uninstall, preventing orphaned
  executables after package removal
