Wire WAYF tooltip aria handlers

# If applied, this commit will
Wire the generic tooltip ARIA handlers into the WAYF callback, add a Cypress regression test for the remember-choice tooltip toggle, and restore the spec to run fully by removing a stray it.only.

# Why is this change needed?
Prior to this change, the WAYF remember-choice tooltip never updated its aria-hidden and aria-expanded state when the label was clicked, so assistive technology received incorrect state.

# How does it address the issue?
This change invokes the existing tooltip accessibility handlers during WAYF initialization and adds a regression test that checks the ARIA state changes.

# Provide links to any relevant tickets, articles or other resources
Found during review of PR #2095.
