Update craftcms project type defaults

[AugustMiller]

The Craft team is gradually shifting its priority to MySQL support over MariaDB, and would prefer this as the default.

This PR also changes the default PHP version to 8.1. New projects/config can still choose their database driver and PHP version via the --database and --php-version flags, if the user desires.

The Issue

MariaDB has slowly drifted away from being a drop-in replacement for MySQL, and this has resulted in some frustration from our community, as well as an increased support burden.

How This PR Solves The Issue

We implemented a new craftCmsConfigOverrideAction function that sets the PHPVersion and Database properties for the current DdevApp, using predefined constants. This function is assigned to the project type’s configOverrideAction so it runs during setup.

Manual Testing Instructions

The current recommended config command…

mkdir ddev-default-db-test
cd ddev-default-db-test
ddev config --project-type=craftcms --docroot=web --create-docroot

…should now produce output like this:

name: ddev-default-db-test
type: craftcms
docroot: web
php_version: "8.1"
webserver_type: nginx-fpm
# ...
database:
    type: mysql
    version: "8.0"

Overrides should still be reflected in the resolved config file, so this command…

ddev config --project-type=craftcms --docroot=web --create-docroot --php-version=8.0 --database=mariadb:10.4

…produces this output:

name: ddev-default-db-test
type: craftcms
docroot: web
php_version: "8.0"
# ...
database:
    type: mariadb
    version: "10.4"

This looks like it should be OK to me. Any thoughts on whether it could impact existing projects? I think it should be OK.

Is the Craft team using mysql:8.0-specific features?

[AugustMiller]

Given that configOverrideAction only comes into effect the first time a configuration is created, I don't see this impacting existing projects.

Craft currently supports MySQL 5.7.8+, but we are evaluating features only available in MySQL 8.x and Postgres for future versions of Craft. We want to put new users in a good place if/when we decide to end support for 5.x (and/or MariaDB).

Edit: We have updated our Minimum + Recommended system requirements to reflect this—basically, this PR brings new DDEV projects into alignment with our official recommendations. 👍

I manually tested and brought up default craft cms site, everything works fine, does what it should. Thanks for this contribution!
