Autorelease

Major changes in this release of autorelease:

* Moving toward requiring trusted publishing on PyPI for releases. See [PyPI docs on adding a trusted publisher](https://docs.pypi.org/trusted-publishers/adding-a-publisher/)
* Dropping any suggestion that we still support either Travis or Azure. This is a GitHub Actions project.

New features

* Deprecations & cleanup ([124](https://github.com/dwhswenson/autorelease/pull/124))
* Trusted publishing ([123](https://github.com/dwhswenson/autorelease/pull/123))

Miscellaneous improvements

* Updates Python versions; unit tests and deploy script ([121](https://github.com/dwhswenson/autorelease/pull/121))

New features

* Switch release notes to GH API 4 ([117](https://github.com/dwhswenson/autorelease/pull/117))

Bugs fixed

* Remove hard-coded notes stuff ([118](https://github.com/dwhswenson/autorelease/pull/118))

Fix packaging error (missing MANIFEST.in).

Bugs fixed
* Require setuptools ([113](https://github.com/dwhswenson/autorelease/pull/113))
* Handle KeyError when package doesn't exist in PyPI ([109](https://github.com/dwhswenson/autorelease/pull/109))

Miscellaneous improvements
* Guard setuptools import ([112](https://github.com/dwhswenson/autorelease/pull/112))

New features
* Add "getattr" version loaders ([104](https://github.com/dwhswenson/autorelease/pull/104))
* YAML config support in the click CLI; release notes in click CLI ([102](https://github.com/dwhswenson/autorelease/pull/102))

Miscellaneous improvements
* Drop Python 2.7; add Python 3.11 ([107](https://github.com/dwhswenson/autorelease/pull/107))
* Add Python 3.10 to testing matrix ([106](https://github.com/dwhswenson/autorelease/pull/106))
* Use the `autorelease check` command locally ([105](https://github.com/dwhswenson/autorelease/pull/105))

This is a minor bugfix release to fix problems that pushing to a stable branch on a fork would trigger the release process. (Leading to confusing errors, since the fork doesn't have the authorization to actually cut a release.)

Bugs fixed
* Prevent actions from running on forks ([100](https://github.com/dwhswenson/autorelease/pull/100))
