Clarify create file palette item (#11799)

## Description
Clarifies the command palette fallback item for creating a new file so
it reads `Create a file named <file-name>…` instead of the more
ambiguous `Create <file-name>…`.

This keeps the existing create-file behavior unchanged and only updates
the user-facing label plus nearby code comment.
