This commit contains multiple refinements for the Google authentication components:

1. CSS rules for hovering over the "quiqqer-auth-google-registration-btn" button have been added.
This provides better feedback on user interaction.
2. In the JavaScript files, the code handling button creation and insertion into the container for
the login control has been revised for better accuracy.
3. Dependencies in the "composer.json" have been updated to their newer versions. Moreover,
unnecessary white spaces have been reduced for better readability.
4. The "autoLogin" configuration has been deleted from "settings.xml".
5. In "Login.html", the previous invisible token field has been replaced with a login button. This
gives users an awareness of the authentication process with Google.
6. In the "Login.php", CSS file "Google.css" has been attached if it exists. It helps in
maintaining a clean and consistent look for the login control.

Across multiple files the code handling Google authentication was simplified and cleaned.
Irrelevant references were removed, unnecessary variables were eliminated and the code was
refactored to consistently use short and clear statements. This helps improving the code
readability and the efficiency of the authentication process. Additionally, the function
`Google::validateAccessToken($token)` was updated to catch a more general `Exception` instead of a
specific `GoogleException`. This covers a wider range of potential errors during the process of
validating the access token, increasing the robustness of the function. Removing a not used
`getSettingsControl()` method from Auth.php simplified this file even more.

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.
