Subject: [PATCH] fix: make MariaDB version detection case-insensitive in tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #7929

The tests used str_contains() for MariaDB version detection, which is
case-sensitive. On some MariaDB installations, the version string
returned by server_info may have different casing, causing the
detection to fail.

Also updated GetVersionTest regex to accept MariaDB version format
'10.11.4-MariaDB-1' which includes a suffix after the numeric version.

Changes:
- ForgeTest: str_contains → str_contains(strtolower(...))
- GetFieldDataTestCase: str_contains → str_contains(strtolower(...))
- GetVersionTest: regex updated to match MariaDB version format
