fix(phpstan): correct exception handling and update code formatting

See merge request !9

Changes made to the .gitlab-ci.yml file to align with the current project dependencies. Quiqqer
package bundle component link has been updated from version 2 to main. This allows the CI/CD
pipeline to use the latest available updates from the main branch. Redundant inputs specifying the
quiqqer-major-version have also been removed.

The commit contains the following main changes:

1. Updated exception handling in `ajax/disconnectAccount.php`. Removed the handling for
`QUI\Auth\Google\Exception`.

2. Significantly reduced ignored errors in `phpstan-baseline.neon`, indicating an overall
improvement in code quality and removal of potential bugs.

3. Applied consistent use of spaces around "|" operator in several method signatures within the
`src/QUI/Auth/Google/Google.php` file.
