feat(editor): add delete key support for table view (#14119)

This PR allows the user to use the `Delete` key to delete the content of
one or more cells in a Table View. Previously, this was only possible to
do with the `Backspace` key. Both keys can now be used, which is often
the norm in other tools - such as Notion and Excel.

In short, the logic for the `Backspace` key has been moved to a separate
function which is called by keyevents from both the `Backspace` and
`Delete` keys.
