Failed to fetch action metadata for actions/c/undefined: 'Not Found'

[jsoref]

Type: Bug

Create a workflow file and type:

jobs:
  something:
     runs-on: ubuntu-latest
     steps:
       - uses: actions/c

get completion for the end of actions/c

expected results: do not try to use /undefined -- I didn't type that and it's clearly a bug.

Fwiw, just opening the workflow with the cursor at - uses: actions/c here triggers this message -- triggered as part of upgrading to:

Note that while you're in the neighborhood, these messages shouldn't be errors.

It is perfectly reasonable for a user to be slowly typing:

      - uses: actions/checkout@v4

And they shouldn't get Error events as they do this:

[Error - 10:52:31 AM] Failed to fetch action metadata for actions/c/undefined: 'Not Found'
[Error - 11:03:39 AM] Failed to fetch action metadata for actions/d/undefined: 'Not Found'

[Error - 11:05:04 AM] Failed to fetch action metadata for actions/checkout/v: 'No commit found for the ref v'

It'd be reasonable to log them as Notice/Info whatever the non Warning/Error category is.
