fix: [M3-7977] - Improve visibility of errors in Linode Config dialog

[mjac0bs]

Description 📝

There were a couple of problems in the Add/Edit Configuration dialog:

• Interface select errors were not always being surfaced.
• ~This was fixed in PR #: General errors were not reliably being focused by scrollErrorIntoView because the scrolling can happen before the general error is updated in form state (via formik.setStatus), and therefore there is no notice to scroll to in the DOM, since generalError being defined is a condition for rendering the notice.~
