Add WPGraphQL version compatibility headers and checks

[theodesp]

Description

This PR introduces custom plugin headers for declaring the minimum required and maximum tested versions of WPGraphQL, and wires them into the plugin's initialization logic. This provides better validation and safer bootstrapping when used alongside WPGraphQL.

Added the following custom headers to the main plugin file:

Requires WPGraphQL

WPGraphQL tested up to

How to Test

✅ Ensure WPGraphQL is installed and activated.

✅ Change the version of WPGraphQL (if needed) to simulate:

• A version lower than Requires WPGraphQL

• A version higher than WPGraphQL tested up to

✅ Activate the plugin:

• If the WPGraphQL version is below the required, the plugin should not continue loading and a WP admin notice should appear.

• If within the compatible range, the plugin should load normally.

✅ Check admin notice behavior:

Go to WP Admin > Plugins and verify the message when versions are incompatible.

Fixes #358

Looks good to me 🚀

Might be worth adding a changeset too for the RP.
