Issue Forms: Add the ability to use value from one input in another (template variables)

[just-joshing]

I want to be able to specify a value in one input that can then be referenced in markdown text.

For example, say I have

  - type: input
    id: name
    attributes:
      label: Name
      description: What's your name?
      placeholder: ex. Jane Smith/John Doe
    validations:
      required: true
  - type: markdown
    attributes:
      value: |
        Thanks, %name%, for taking the time to fill out this bug report!

Whatever text the user specifies in the "name" input, I want to be able to use it in the markdown text, replacing %name%.

My use case: I know I can add URL query params to auto-populate inputs in forms today. I create links with different pre-populated values that I share with my team to help them more quickly create issues with the appropriate fields already pre-filled out. But I also have some lengthy markdown I want to add to my template that would make use of those pre-filled inputs to generate more links to other resources/insights or related things. Putting the lengthy text I want in the URL query params isn't possible/practical (and I don't want the user to be able to edit the lengthy text directly in something like a textarea), so I want to be able to take the short inputs and reuse them, potentially multiple times, in markdown inputs I have in the issue form/template.

+1 I would love it to be like git actions if, where it is possible to access the context object to get task results matching the task id. id is already defined by forms, seems appropriate.
