feat: add info on what should occur post-transfer

[CBID2]

Why:

@derisen is trying to transfer the ownership of several OAuth apps to an another organization. However, the app's current organization admins are unsure where they can approve the request.

Closes:
Closes #22565

What's being changed (if available, include any code snippets, screenshots, or gifs):

This pull request provides information on what occurs once they give OAuth apps to another person. See screenshot below for reference.

Note to Reviewers

I'm unsure if I should add the information as two steps or place them in a subsection titled "What Should The New Owner Expect". Suggestions are welcomed! :)

Thanks so much for opening this PR @CBID2 ⚡ ✨

I'm unsure if I should add the information as two steps or place them in a subsection titled "What Should The New Owner Expect". Suggestions are welcomed! :)

Great question. Since it could be a different person who transfers the app vs completing the transfer, I think it makes sense to leave the info about the final completion actions outside of the procedural list. (So it's more noticeable if someone comes looking for that info.)

We could put it in a subsection as you mentioned, although it would be a very short subsection 😄 So I'm thinking to keep it simple and just place it as a new paragraph below the existing procedural steps.

I'll go ahead and make that change, and we'll get this merged as soon as tests are passing.

Thanks for your help improving GitHub's documentation!
