Modules Admin: Allow VideoPress module to be managed for any plan

[roundhill]

This is a follow-up to #21006 where we add support for the Jetpack VideoPress product and enable it for free sites. We missed that there was a separate module management page in Jetpack that needed changes to support this same functionality.

The VideoPress module will now be able to be activated by any plan, including free:

Testing instructions:

• Apply D66710-code to your wp.com sandbox if it hasn't been merged yet, sandbox public-api.wordpress.com, and enable JETPACK__SANDBOX_DOMAIN on your Jetpack dev site so that it points to your wp.com sandbox. You also may need to enable HTTP access on your WP.com sandbox.
• On your WordPress.com sandbox, enable the feature flag for Jetpack VideoPress in mu-plugins/videopress/constants.php: define( 'VIDEOPRESS_JETPACK_VIDEO_ENABLED', true );
• Remove all plan/upgrades so you are on the free Jetpack plan.
• Visit the dashboard, then click on Modules at the bottom of the screen.
• You should be able to activate the VideoPress module.
• Also try activating the module with the bulk-select tool, it should work.
• Head over to the media library and upload a video. If no videos were uploaded to the site previously, it should be uploaded successfully.
• Any video uploaded after the first upload should error out.
