Today while creating a cdk server adapter, I noticed there is a new Edit button when selecting credentials for the adapter. This was recently added here: JBIDE-23382

I would like to propose a change to make it consistent with other things like JREs when creating a server adapter.

So in the server editor, we used to have just Add.. and now we also have Edit...:

Similar thing in the New Server adapter.

Now look at the New Runtime dialog:

I think it would be nice to do it similarly, wdyt?
Meaning, instead of Edit.. and Add.., we would simply have a button for "Credentials..." which would open the appropriate Preference page (and upon closing, you would need to update the content on the page to show any added credentials).
