Security fix cf8b9ad needed migration
`zerver/0501_delete_dangling_usermessages` on the 8.x branch (3db1733).
This resulted in two migrations numbered 0501, due to which this tool
always got stuck on 0501.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

Because of a security release that required a migration, there
are two migrations numbered 0261. To avoid breaking existing
installs renumbering the migrations, we skipped migration 0261
when running tools/renumber-migrations.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Tweaked by tabbott to not remove it from lister.py, linter_lib, and
friends, since those are intended to support both Python 2 and 3
(we're planning to extract them from the repository).
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
Previously, if you have a branch with a new migration,
and you rebase onto master past someone else's migration,
you have to manually renumber your migration.
Add a script that automatically renumbers the migrations.
Fix#4257.
