Bump to PHP 7.2 and WP 6.6

[kraftbj]

With WordPress 6.6+ requiring PHP 7.2 as a minimum, we can bump this up now.

Hmm, I'll need to dig into the CI since it looks like it assumes we're developing on an older version of PHP.

• Phive -> add A978220305CD5C32 to hashes
• lock file -> you may be developing on PHP 8.1 and that generated the lock file

@szepeviktor Can you walk me through the strict validation on the composer.lock/json file in the code standards test? Given that it doesn't happen with the locked unit test runs, I'm curious if it is needed, etc.

Related, what version of PHP should the composer file be rendered with? I'm wondering if there is a specific PHP version that I need to target (beyond 7.3 or 7.4)?

Given that it doesn't happen with the locked unit test runs,

composer validate runs only in the Coding Standards job.
But there is a warning there too https://github.com/Automattic/wordbless/actions/runs/13073688399/job/36480621792?pr=67#step:7:14

Modifying composer.json needs a lock file update.

Modifying composer.json needs a lock file update.

I realize that, but locally, there aren't any changes to composer.lock after running composer update.
