Create form field number

[Devessier]

• Refactor VariableTagInput to have a reusable low-level TipTap editor
• Create two primitive form fields:
  • Text
  • Number
  • Boolean

Notes:

• We could refactor the VariableTagInput to fully use components from FormFieldInput.

To do:

• [ ] Put isTextField(), isNumberField(), etc. calls in a separate FormField component that we can reuse across actions
