Bump coverage from 7.8.2 to 7.9.1 in /requirements

[dependabot]

Bumps coverage from 7.8.2 to 7.9.1.

Changelog

Sourced from coverage's changelog.

Version 7.9.1 — 2025-06-13

• The "no-ctracer" warning is not issued for Python pre-release versions. Coverage doesn't ship compiled wheels for those versions, so this was far too noisy.

• On Python 3.14+, the "sysmon" core is now the default if it's supported for your configuration. Plugins and dynamic contexts are still not supported with it.

Version 7.9.0 — 2025-06-11

• Added a [run] core configuration setting to specify the measurement core, which was previously only available through the COVERAGE_CORE environment variable. Finishes issue 1746_.

• Fixed incorrect rendering of f-strings with doubled braces, closing issue 1980_.

• If the C tracer core can't be imported, a warning ("no-ctracer") is issued with the reason.

• The C tracer core extension module now conforms to PEP 489, closing issue 1977. Thanks, Adam Turner <pull 1978_>_.

• Fixed a "ValueError: min() arg is an empty sequence" error caused by strange empty modules, found by oss-fuzz_.
