This is no longer an accessible alert. We'd need to use
aria-invalid="true" on the input and then
aria-describedby on the input to connect to the id of the ErrorMessage
component.

We realized we probably want to re-engineer GafaelfawrUserMenu around
the Radix NavigationMenu. To make space for that new component, we'll
rename the DropdownMenu-based component. This will probably get deleted
later once the new user menu is commissioned.

This adds the component and a basic storybook based on the original
GafaelfawrUserMenuDropdown component. We'll add the Radix Navigation
Menu implementation next.

This is now semantically correct and accessible user menu. We still need
to tweak the presentation of the menu content so it pop down below
trigger.

This makes the menu functional... but we haven't yet replicated all the
fun animation functionality that's provided in the Radix example at
https://www.radix-ui.com/primitives/docs/components/navigation-menu

This new menu is in the @lsst-sqre/squared package.

- It seems that the a selector on the nav bar is overriding the
  specificity of the color rule on MenuLink, so I had to add important!
  there. This needs to be fixed.

  - Adjusted positioning of the drop down menu so it appears on the
    screen.

This makes it easier to develop the user menu...

This should ensure that squared and rubin-style-dictionary are always
rebuilt before running squareone in dev mode.

This was causing the menu bar to shift up after log in.
