GH Actions/verify release: tweak the workflow [1]

As of PHPCS 4.0.0, a new "No files were checked" error will be shown if `phpcs`/`phpcbf` runs a scan and no files end up being scanned.

Previously, to test that the downloaded PHAR file is nominally functional, the `php ${{ steps.source.outputs.FILE }} . -e --standard=PSR12` command was used.
For `phpcs`, this would "explain" the PSR12 standard, for `phpcbf`, this would spin up PHPCS and end up not scanning anything as there are no files in the working directory, but it did test that the PHAR file was functional.

This "trick" will no longer work with PHPCS 4.0.0 due to the new "No files were checked" error, so I'm switching the command to `-i`, which should work cross-version and on both `phpcs` as well as `phpcbf`.
