PHP 8.4 - Modify Lando recipe so can test under PHP 8.4

[yorkshire-pudding]

... it has been a challenge getting the lando testing environment to work with PHP 8.4, primarily due to how the newer PHP image uses newer database command line clients that cause all sorts of issues. See here if you are interested: lando/php#167

In my attempts to find a solution, I have made some draft changes to Bee that should be documented. To start I will create a list here, but may well create individual issues for some of these:

• Lando's PHP images use the MariaDb client tools with symlinks from MySQL named ones to these; newer versions of the MariaDB client deprecate the use of symlinks.
• Newer versions of the mariaDB client tools also seemed to verify the SSL server certificate which caused problems.
• I have made the Lando machine install the MySQL client tools to remove this; for MySQL this will reflect most MySQL server, though I may need to start testing with MariaDB separately, at least for the DB tests.

Note there is an issue to try and get a sustainable fix that isn't a workaround: lando/lando#3833

There is now some movement with a change to the PHP image so it will detect the database being used and use the correct client. This has been merged so just waiting for a release to test it.
