Changes proposed in this Pull Request:

On WordPress older than 5.9 with PHP 7.4, two spots could stop the site with a fatal error: saving some settings, and adding a membership field in the form builder. They now use a check that works on every supported version. Nothing changes for users on newer setups.

Part of themegrill/user-registration-pro#1963.

How to test the changes in this Pull Request:

1. On WordPress 5.8 with PHP 7.4, open a registration form in the builder and add a Membership field. It should add without an error.
2. Save the plugin settings. They should save without an error.
3. Repeat on the latest WordPress and PHP. Same result as before.

Types of changes:

• Bug fix (non-breaking change which fixes an issue)

QA suite — refused, no regression spec

This PR changes product source but adds no spec, so the suite was
refused before booting WordPress — running it just to report the same
thing at the end costs runner minutes for nothing. Run
/claudegrill:verify-fix locally and let write-spec add the guard
to this branch, then push again.
