* Allow running twisted trunk against other branches

I would like to do this so we can try Synapse's typechecking against a
specific branch that the project solicited tests for, see
https://mail.python.org/archives/list/twisted@python.org/message/GGO5JHA5S475AK6JZ3GCC3GIHGKQYM6Y/

Bump dtolnay/rust-toolchain from e645b0cf01249a964ec099494d38d2da0f0b349f to 9cd00a88a73addc8617065438eff914dd08d0955 (#14968)

* Upgrade to new lockfile format

Now requires poetry >= 1.2.2 to read and poetry >= 1.3.0 to write.

Cheat sheet:

```
poetry --version
poetry show > scratch/before
pipx upgrade poetry
poetry --version
poetry show > scratch/after
diff scratch{before,after} && echo "no change!"
```

* Use Poetry 1.3.2 when reading or writing lockfile

* Remove unneeded(?) poetry dep for cibuildwheel

* Update docs

* Remove redundant call to setup-python

* Remove outdated comments related to Poetry 1.x

* Remove outdated docs line

was fixed in #13082

* Minor improvements to poetry cheat sheet

* Invoke setup-python-poetry with explicit version

Not sure about this. It's hardcoding versions everywhere.

* Changelog

* Check the lockfile is version 2.0

Might one day incorporate other checks like #14742

* Typo fixes, thanks Sean

Since github always scrolls to the bottom of any test output, let's put the
failed tests last and hide any successful packages.

* Allow unused ignores in "bleeding edge" CI

Where "bleeding edge" means the Twisted Trunk and Latest Deps jobs.

Follow up from #12531.
Resolves #12574.

* Use `--extras all` in latest deps mypy CI

Twisted trunk job already does this.

Missed in #12531.

* changelog

This reverts commit 5a320baa.
This reverts commit f282d5fc.
This reverts commit ce6ecdd4.

Where "bleeding edge" means the Twisted Trunk and Latest Deps jobs.

Follow up from #12531.
Resolves #12574.

Fixes #12458

Setting `update_existing: true` in the `create-an-issue` GitHub Action
will avoid opening duplicate issues if an open issue already exists with
an identical title.

If no open issues match the title, then a new issue will be created.

This helps avoid spamming our issue tracker should there be a failure
when testing against Twisted's trunk.

This PR also pins the SHA of the `create-an-issue` action to mitigate
the risk of a malicious actor gaining access to JasonEtco's account.

This creates a GHA workflow which runs at 8am every day, and runs mypy, trial and sytest against Twisted's current trunk. If any of the jobs fail, it opens an issue.
