Adding "10up Suggested" tab to plugin page using action instead of filter

[morganestes]

It's a minor point since technically it works to use add_action() instead of add_filter(), but 'install_plugins_tabs' isn't an action hook, so the plugin should use
add_filter( 'install_plugins_tabs', __NAMESPACE__ . '\tenup_plugin_install_link' ); instead of add_action() on https://github.com/10up/10up-experience/blob/develop/includes/plugins.php#L56.
