Prevent overwriting changes to prefilled data in model catalog register form

[mturley]

Resolves https://issues.redhat.com/browse/RHOAIENG-21573

Description

This is a hacky fix, a better fix would be to refactor this page so it fetches catalog data before mounting its state hook and avoids prefilling in a useEffect. Opened a followup issue for that refactor: https://issues.redhat.com/browse/RHOAIENG-21678

How Has This Been Tested?

• Go to Model Catalog, click on a model
• Click "Register model"
• Edit one of the fields in the form
• Wait at least 30 seconds
• See that your edits are not reset to the initial prefilled data

Test Impact

I attempted to write a Cypress test for this and ran into issues. This fix is low-risk and easy to verify - following up to add a test is covered in the tech debt issue https://issues.redhat.com/browse/RHOAIENG-21678. See that issue's description for context on the trouble I had.

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit or cypress tests for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change.

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main
