Feature description

I was using PaginatedFieldMessageEmbed and I added my own custom actions (functional equivalents of 'back', 'forward', and 'submit'). Went to run it and I was confused why they weren't showing up. I did some digging and it seems like actions (exlcuding page specific actions) are only added if the number of pages is greater than 1, which in my case they weren't. While this was fine for the 'back' and 'forward' actions, I needed the 'submit' action to show at all times.

Desired solution

It would be nice if there was a method like setPersistentActions that added actions regardless of page count. Alternatively, add a property on PaginatedMessageAction like persistent?: boolean to indicate that the action should persist on all pages.

Alternatives considered

For now, I can work around this limitation by doing the following:

const paginatedEmbed = new PaginatedFieldMessageEmbed()
  .setActions([ /* 'back' and 'forward' actions */ ])
  .make();
const submit: PaginatedMessageActionButton = { /* stuff */ };
for (let i = 0; i < paginatedEmbed.pages.length; i++) {
  paginatedEmbed.addPageAction(submit, i);
}
paginatedEmbed.run(interaction);

If there is only 1 page then going 1 page forward just loops back to the same one page, same for backwards. The buttons would do nothing and would be purely there for aesthetics and bad UX. That said, you can already achieve this by setting .defaultActions property on the PaginatedMessage (or PaginatedFieldMessageEmbed in your case).
