Plugin header does not include requirements used by core

[aaemnnosttv]

Bug Description

As per https://developer.wordpress.org/plugins/wordpress-org/how-your-readme-txt-works/, as of 5.8 WordPress core no longer sources plugin requirements from its readme.txt file, but instead from the plugin's header in its main php entrypoint.

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• The following headers should be mirrored from the readme.txt to google-site-kit.php
  • Requires at least Minimum required version of WP
  • Requires PHP Minimum required version of PHP

Implementation Brief

• Copy the headers and their current values in the ACs from readme.txt to google-site-kit.php
  • Note the readme is plain text where as the headers in the plugin php file need to be added to the existing plugin header comment block. E.g.

    site-kit-wp/google-site-kit.php

    Line 19 in 43693b6

    * Text Domain: google-site-kit

Test Coverage

• No changes needed

QA Brief

• It's difficult to QA this change until the plugin is installed, because the data isn't displayed in the UI until the plugin is installed/the data is viewed on the WordPress plugin site. So there's really no QA to do for this issue and QA can be skipped for this one.

UPDATE: This is still odd to QA outside code, so I wrote a unit test that verifies the info we provided is used. If the PHP Unit tests for test_plugin_data pass, then if you change the value for Requires at least: in google-site-kit.php to 5.0 and the tests fails: this is good 🙂

Changelog entry

• Add required versions of PHP and WP to plugin header.
