This works for me on version 2.48.0.  It seems to have been fixed in
2.43.0.  You would have to update to a newer version.

It looks like it was fixed in 4adceb5a299 (diff: fix --merge-base with
annotated tags, 2023-10-01).[1]  The intent of the error message was to
disallow non-commit-ish like trees:

    v2.48.0^{tree}

But it also rejected annotated tags instead of peeling them.
