WP 7.0: Set 7.0 as our minimum supported version

[dkotter]

Note

Branched from #271. Will open this once that is merged.

What?

Partially closes #244

Updates our minimum version of WordPress to 7.0

Why?

Going forward, we are relying on the AI Client that is shipping in WP 7.0. As such, we're setting that as our minimum required version

How?

• Update any references to 6.9 to 7.0

Use of AI Tools

None

Testing Instructions

Nothing to test here. Similar to #244, the plugin shouldn't throw any fatal errors on 7.0 but full functionality won't work there yet

Note

Unit and E2E tests are failing. Those will be fixed up once full 7.0 support is in place.

May be best to remove the WP and PHP requirements from this doc and allow the readme to be the doc-based source of this info? We could link to the readme from here, but I worry about having this info in multiple places and forgetting to update this one in the future.
