Mysql 5.7 - FloatAnonymizer - strict comparisons are not respected

[SimonMellerin]

Continuous Integration job randomly fails on FloatAnonymizerTest with this error message:

1) MakinaCorpus\DbToolsBundle\Tests\Functional\Anonymizer\Core\FloatAnonymizerTest::testAnonymizeWithPercent
Failed asserting that 19.0 is equal to 19.475 or is greater than 19.475.

See https://github.com/makinacorpus/DbToolsBundle/actions/runs/12046730125/job/33588042824 for example.

To avoid false positive in our CI actions, as this is a well known issue, for now, we will skip this test for MYSQL 5.7.
