 Since Saturday August 23rd the PHP 8.3 and 8.4 workflows are failing due
 to the test containers being unable to connect to MySQL/MariaDB.

 > Error: Failed to get current SQL modes. Reason: ERROR 2026 (HY000):
 TLS/SSL error: Certificate verification failure: The certificate is NOT
 trusted.

 Several factors have changed since the last successful run (needs
 verifying):

 * Actions runner container image (from Debian Bullseye to Trixie)
 * PHP (from 8.4.10 to 8.4.11 and from 8.3.23 to 8.3.24)
 * OpenSSL (from 3.0.16 to 3.5.11)
 * Possibly more

 Needs investigating to identify the root cause.
