Insert.php can’t be translated.

Hi there! Thank you for writing this gem of a plugin! I use it quite often on my websites and as a GTE for nl_BE, I try to keep it as translated as possible. Recently, some of my co-workers who also use this plugin say that when you want to insert a shortcode in the block editor, a lot of English text is displayed.

So, I looked around and the whole “insert.php” in the admin folder doesn’t have a textdomain attached to it. Can this be solved in a future version so it can be translated? That way the important warning at the bottom for example can be translated to the native language of the editor.
