release: release version 0.17.0

Thanks to everyone who's contributed!

Unlike previous releases, I went through the changelog entries and
reorganized them a bit.

We didn't have anything under "Deprecations" this time, but I moved
the heading after "Breaking changes" for next release. I think
breaking changes are more important because deprecations are just
about giving a heads up before it actually breaks.

release: release version 0.15.1

This release is just so we can publish the crates to crates.io. We
couldn't publish the 0.15.0 crates because `jj-lib-proc-macros` had
`publish = false`.
