Prevent DB warnings in unit tests

[mikkamp]

Changes proposed in this Pull Request:

This PR reverts the change in #335 since it still produces warnings when starting tests with an empty database. So here we revert to an earlier hook and add a filter to prevent the notice from showing. We also use WC_REMOVE_ALL_DATA so all database tables can be removed and recreated when WC_Install is called.

The PR also adds PHP version 8.3 to the workflow, so it now runs the default tests on PHP 8.2 and includes the oldest supported version (7.4) and the latest supported version (8.3).

Closes #338

Detailed test instructions:

1. Install unit tests with a version of WC > 8.3 bin/install-unit-tests.sh <db_name> <db_user> <db_pass> (select Y to clear database during install)
2. Run unit tests vendor/bin/phpunit
3. Confirm there are no longer any warnings when the tests are run
4. Check the Workflow tests and confirm we have successful runs for PHP 7.4, 8.2, 8.3

Thanks @mikkamp I don't see anymore the errors in the console and the tests pass. Also now the file seems consistent with the AW one.

❓ In woocommerce/google-listings-and-ads#2183 you mentioned that we should mark extensions as compatible with PHP 8.3, Should we mark this one as Composer as well as the tests run smoothly? Or it's any other step to take?

I've been marking them as compatible in the project thread: peeuvX-19l-p2
I'm not sure I follow about marking it as compatible in composer, I don't recall us generally setting any max PHP version, at most we have extensions which set a minimum PHP version: https://github.com/woocommerce/google-listings-and-ads/blob/2.5.13/composer.json#L8
But that's only for extensions that include composer packages in the release.

What I meant about composer is that Composer install runs successfully. As far as I read that's a condition to make it compatible.
