test-install: add new glob for the upgrade notice in newer versions of pip We only globbed for the old warning, newer versions of pip use a cleaner one.

WIP test new CI image

rust: use `.cargo/config.toml` instead of `.cargo/config` This has been deprecated for a while now and we don't support Rust versions that only understand the old path.

rust: apply clippy lints They are at most harmless and at best make the codebase more readable and simpler.

rustfmt: format the codebase with nightly-2024-07-16 The CI has moved to a newer nightly, which slightly changes how it wraps comments (which is the very option we use nightly for).

hghave: update detection of black version to a newer minimum The CI has moved to version 23.3.0, which is the last one to support 3.7 at runtime.

black: format the codebase with 23.3.0 The CI has moved to 23.3.0, which is the last version that supports 3.7 at runtime, so we should honor this change. # skip-blame mass-reformating only

pytype: work around wrong ImportError flagging As documented in https://github.com/google/pytype/issues/163, newer versions of Pytype do not understand caught `ImportError`, so we temporarily ignore them where applicable.

zeroconf: fix boolean return value This was (wrongly) flagged by Pytype as being undefined since it doesn't seem to understand `try` blocks. However, the caller is expecting a boolean and the fix to appease Pytype is simple, so we do both.
