General: Update minimum WordPress version to 6.8 (#46801)

This updates the minimum WordPress version for our plugins (other than
CRM and VaultPress) to 6.8, as we support only the current and previous
versions. This is considered a "major change".

TODOs and other compatibility code will be cleaned up in a subsequent
PR.

Committed via a GitHub action: https://github.com/Automattic/jetpack/actions/runs/21483736019
