I think it wouldn't hurt to also update frontend/src/pages/connectionTypes/manage/EditConnectionTypePage.tsx

But I tested the create connection type and it looked good

Good point. I tried this and you can edit the name of the resource to be the same name as another connection type.

I think we probably want to prevent this. Leading back to the other discussion of checking for duplicate names before attempting to save. @christianvogt Thoughts?

@jeff-phillips-18 let's start a conversation about showing the k8s resource name in the UI. No need to handle duplicates as part of this work.
