Replace serverVersion example values with full version numbers

Doctrine DBAL 3.6.0 deprecated incomplete version numbers for the serverVersion
value (for example 8 or 8.0 for MySQL). Instead, a full version number (8.0.37)
is expected.
See https://www.doctrine-project.org/projects/doctrine-dbal/en/4.0/reference/configuration.html#automatic-platform-version-detection
and https://github.com/doctrine/dbal/blob/4.0.x/UPGRADE.md#bc-break-disallowed-partial-version-numbers-in-serverversion.

This commit replaces partial version numbers with full version numbers.
It also replaces examples with EOL database versions (such as MySQL 5.7 and
PostgreSQL 11) with more modern, supported versions.

Fixes #19876.
