Switch to php 8.2 as the default

[tomjn]

Switch to 8.2 as the default PHP, 8.0 is no longer supported, 8.1 is security fixes only, and 8.3 is brand new, so 8.2 it is!

If people need 8.0 or other versions they can use the core extensions

Also noting that a number of hosts are skipping 8.1 as an option, e.g. WP Engine, and VIP is on 8.2
