fix: Align pyproject.toml with contribution guide

[ArnabTechiee]

Description

This PR fixes a bug in the developer setup process where the installation command from the CONTRIBUTING.md guide would fail.

The failure was caused by a mismatch between the dependency group definitions in pyproject.toml and the --extra flags used in the guide's command. This change aligns the pyproject.toml file with the documentation by moving the dev and docs dependency groups to [project.optional-dependencies] and adds the missing pre-commit package to the dev group.

This ensures a smooth setup experience for new contributors.

Closes #1970

Pull request overview

This PR fixes a developer setup issue where the installation command documented in CONTRIBUTING.md would fail due to a mismatch in dependency group definitions.

Key Changes:

• Moved dev and docs groups from [dependency-groups] to [project.optional-dependencies] to enable --extra flag usage
• Added pre-commit package to the dev dependency group

The pre-commit package should include a version specification for consistency with other dependencies in this file. All other dev dependencies specify minimum versions (e.g., pytest>=7.2.2, tox>=4.11.4). Consider adding a version constraint like "pre-commit>=3.0.0" to ensure compatibility and prevent potential breaking changes from future versions.
