fmt: correct documentation for Formatter

Before this CL, the documentation for Formatter suggested that
implementers of Format(f State, verb rune) could use Fprint(f) or
Sprint(f) to generate output. The Sprint(f) suggestion however is
invalid.

Fix that by simply suggesting Sprint() alongside Fprint(f).

Fixes #60358
