E713 test failing on text inside double quotes

[adamloverro]

how did you install flake8?

Initially, flake8 was run with pre-commit;
.pre-commit-config.yaml:
  - repo: https://github.com/pycqa/flake8
    rev: 6.0.0
    hooks:
      - id: flake8
        args: [
          # E501 let black handle all line length decisions
          # W503 black conflicts with "line break before operator" rule
          # E203 black conflicts with "whitespace before ':'" rule
          '--ignore=E501,W503,E203,C901,E202' ]

unmodified output of flake8 --bug-report

  "platform": {
    "python_implementation": "CPython",

    "system": "Darwin"
  },
  "plugins": [
    {
      "plugin": "mccabe",

    },
    {
      "plugin": "pycodestyle",
      "version": "2.14.0"
    },
    {
      "plugin": "pyflakes",
      "version": "3.4.0"
    }
  ],
  "version": "7.3.0"
}

No errors to be emitted

what did happen

flake8...................................................................Failed
- hook id: flake8
- exit code: 1

tests/integration/test_azure_integration.py:116:40: E713 test for membership should be 'not in'

sample code

  if "authentication" in str(e).lower() or "credential" in str(e).lower():
      pytest.skip(
          f"Managed identity not available in current environment: {e}"
      )

commands ran

$ pre-commit run --all-files
...

Hypothesis

Rule E713 is triggered by this line of code because it probably matches the pattern if ... not availabile in .... This shouldn't apply in this scenario though since the not available in text is part of a string, and not part of the main if statement logic.

please read the issue template and report to the right place (if it's actually a bug as you're using a very very old version)
