Improve AUR workflow to publish only on PKGBUILD changes

The workflow now checks if PKGBUILD or PKGBUILD-BIN files have changed before publishing the corresponding AUR packages. This prevents unnecessary publishes and streamlines the manual AUR publish process. Also, the workflow_dispatch input for tag selection was removed.
