TOMLDecodeError in `pyproject.toml` due to invalid `opencv-python` declaration

[Ad7amstein]

When running pip install -e ., the following error occurs:

TOMLDecodeError: Invalid value (at line 21, column 5)

This is caused by an invalid line in pyproject.toml:

opencv-python = "^4.6.0"

# Invalid inside an arry
dependencies = [
    "PyPDF2",
    "matplotlib",
    "pyyaml",
    "frontend",
    "pymupdf",
    opencv-python = "^4.6.0"
]

This is not valid TOML syntax inside an array. It should be changed to:

"opencv-python>=4.6.0"

# The corrected line is valid inside an array
dependencies = [
    "PyPDF2",
    "matplotlib",
    "pyyaml",
    "frontend",
    "pymupdf",
    "opencv-python>=4.6.0"
]

This fix resolves the issue and allows editable install to work.
