Don't show "Move to Trash" link if current user cannot delete posts

[ocean90]

Describe the bug
Noticed this while working on #23119. The current component has no checks for current user's capabilities. But there are three that need to be checked: delete_posts, delete_others_posts, and delete_published_posts.

To reproduce

• Create a user with only read and edit_posts capabilities
• Create a new post and click the trash link.
• You'll get the "Sorry, you are not allowed to delete this post." error notice.

Expected behavior
If the user has no access to delete posts the link should not be displayed.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
This probably needs a patch for core to extend the checks in WP_REST_Posts_Controller::get_available_actions() too.

On a second thought, we might be able to use the existing select( 'core' ).canUser() for the check.
