docs(tooling): state the source-resolution re-baseline against this branch's merge base (#14062)

The absolute program totals moved under the branch because #13284 landed two
`tsconfig.typecheck.json` on main in between; the delta this change is
responsible for (+13 programs, +1 entry, +27 pairs) did not. Both readings are
recorded so the number in the file matches what `--list` prints today.
