[BUG] Incorrect additional_dependencies documentation to run prospector as a pre-commit hook with mypy support

[jdechicchis]

Describe the bug

The documentation for additional_dependencies to run prospector as a pre-commit hook with mypy support appears incorrect.

To Reproduce

Follow the instructions at https://github.com/landscapeio/prospector/blob/master/docs/pre-commit.rst with pre-commit config:

- repo: https://github.com/PyCQA/prospector
  rev: 1.10.0
  hooks:
  - id: prospector
    additional_dependencies:
    - .[with_mypy]
    args: [--with-tool=mypy]

Run pre-commit and get error:

cannot run tool mypy as support was not installed.
Please install by running 'pip install prospector[with_mypy]'

Now change pre-commit config to (note the change in underscore with_mypy to hyphen with-mypy):

- repo: https://github.com/PyCQA/prospector
  rev: 1.10.0
  hooks:
  - id: prospector
    additional_dependencies:
    - .[with-mypy]
    args: [--with-tool=mypy]

pre-commit runs as expected

Expected behavior

Following the docs should lead to running prospector with mypy support in pre-commit without error.

Environment (please complete the following information):

• OS: macOS
• Prospector version: 1.10.2
• Python version: 3.11.5
• pre-commit version: 3.4.0

Additional context

Happy to make a PR to update the docs!
