Fix inconsistent "remove" in description of refresh tokens (#23073)

As Refresh tokens are created in HA the corresponding verb is "delete", not "remove".

All buttons and menu items in this context use the correct verb, except for the description which contains "remove", twice.

This commit fixes that.
