Bump flake8-isort from 5.0.0 to 6.0.0 in /requirements

[dependabot]

Bumps flake8-isort from 5.0.0 to 6.0.0.

Changelog

Sourced from flake8-isort's changelog.

6.0.0 (2022-12-22)

• Drop isort 4.x support. [gforcada]

• Add support for flake8 6.0.0. [gforcada]

• Add --isort-no-skip-gitignore option to allow temporarily overriding the set value of isort's skip_gitignore option with False. This can cause flake8-isort to run significantly faster at the cost of making flake8-isort's behavior differ slightly from the behavior of isort --check. [gschaffner]

5.0.3 (2022-11-20)

• Fix broken add_options method, again. [casperdcl]

5.0.2 (2022-11-19)

• Fix broken add_options method [casperdcl]

5.0.1 (2022-11-18)

• Improve the config option is added and read back. [gforcada]

• Bump plugin version. [gforcada]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
