Update/wp version

[jeffpaul]

What?

I tested the AI plugin on WP 7.1 RC3 and things appear to work as expected. This PR bumps the tested-up-to version to 7.1 and leaves the plugin minimum at 7.0. Since trunk is effectively 7.2 and latest will be 7.1 come next Wednesday, I tried to add to the CI test flow another entry to explicitly test against WP 7.0 as that will no longer be latest by Wednesday and want to ensure we're still testing the plugin minimum in our test workflows. So assuming I got the nomenclature correct, it'll be double testing for the next six days but at least as soon as 7.1 is available we'll still be testing on 7.0.

Copilot summary
