fmt: split package documentation into more sections
The package-level documentation on fmt previously had only two formal sections, for printing and scanning. Because of this, the section on printing was very long, including some pseudo-sections describing particular features. This feature makes those pseudo-sections into proper sections, both to improve readability and so that those sections have hyperlinks on documentation sites. Fixes #46522 Change-Id: I38b7bc3447610faca446051da235edcbbd063f61 Reviewed-on: https://go-review.googlesource.com/c/go/+/324349 Reviewed-by: Rob Pike <r@golang.org> Reviewed-by: Dmitri Shuralyov <dmitshur@golang.org> Run-TryBot: Dmitri Shuralyov <dmitshur@golang.org> TryBot-Result: Go Bot <gobot@golang.org> Trust: Tobias Klauser <tobias.klauser@gmail.com>
