Make a docstrings assistant as a script, using AI. The idea would be to have a function

docstrings(;
    code="file_with_code.jl", # this file may contain docstrings to update and code without docstrings to add
    tests="file_with_unit_tests.jl", # optional
    doc="file_with_examples_of_docstrings.jl", # optional
)

that returns raw text containing the code with updated / added docstrings. The code must not be changed.

• Could be great that this function would be written in Julia. Otherwise, some Python is ok.
• The prompt to AI must be very precise.
