[Forms DB] Add field on Drupal form content type to indicate there's a react component for a particular form

[FranECross]

Description

Add an on/off checkbox field on Drupal content type to indicate there's a react component for a particular form.

From Eric Tilberg in this Slack thread:
The official name is Form Upload. I've been referring to the widget as the "form upload widget" and the front-end process itself has been the "form upload flow". (It sounds kind of ridiculous to call it the "form upload form", especially since on the vets-website side, we aren't using the normal scaffolding that we use for our simple forms).

Default is unchecked
Named: Form Upload
Machine name: TBD
Help text: TBD
Location on edit page: TBD
Initial value: Empty

User story

AS AN engineer working on the Form Upload feature
I WANT a field in Drupal that will indicate if there is a react component for a particular form
SO THAT I can present the Veteran, their caregiver, family member or survivor with the Form Upload feature

Acceptance criteria

• New boolean/checkbox field exists on Events
• Graphql changes are documented for FE

@FranECross did we get an update on the location of this field on the VA Form form?

[FranECross]

Ohhh, thanks for the reminder, @dsasser ! I snoozed on that question and will ask now. Stay tuned!

Update 5/13/24

The PR is pending approval.
FE graphql change has been communicated to Eric and his PR has been updated accordingly.

Once we get this merged, we'll need to wait for the CMS to release before Eric's PR will pass tests. Once tests pass there, Eric will finally be able to merge in his changes to content-build.
