write changelog for v0.4.0

Note that we're starting to recommend a particular Go version for
building gofumpt, as that is the go/printer version we've tested the
most with, and a consistent version will also bring consistent behavior.

See #244.

prepare changelog for v0.3.1

And start adding links for the major changes, so any interested users
can read more into each topic.

We also make the release links use the "v" prefix for consistency.

write changelog for v0.3.0

While writing it, I also noticed that the second change for #73,
where we now separate ") {" even if there's no empty line,
wasn't documented in the README. It now is.
