fix: improve error message when mvcgen cannot resolve spec theorem (#12530)
This PR improves the error message when `mvcgen` cannot resolve the name
of a spec theorem.

Example:
```lean
/-- error: Could not resolve spec theorem `abc` -/
#guard_msgs (error) in
example : True := by mvcgen [abc]
```

This used to print the syntax object representing the ident "abc".
