Can't delete players on mobile

[krazkidd]

1. Navigate to /lineup/lineup.
2. Add a player.
3. Select the player <div> element so that it is focused/highlighted.
4. ???

On desktop, you delete a player by pressing backspace in step 4. This is not possible on mobile without somehow manually pulling up the keyboard.

This can be fixed in a couple of ways, either:

a. Use long press event to trigger a prompt.
b. Delete the player if the user has the name input field focused and they press backspace when the field is empty. (This should ideally also trigger a prompt but a new issue can be created for that.)

If a prompt is added, it should be a PrimeVue dialog encapsulated in an SFC.
