Unable to specify lines of context while doing diff (-U flag)

[bentotten]

Currently there does not appear to be a way to specify the lines of context desired while using the git function

For example:
git diff -U0 efefe435

It would be useful to add this to the api so that this command could be executed:
diff = commit.diff(parent, create_patch=True, lines_of_context=0)

In this function, lines_of_context could be added to the function:

GitPython/git/diff.py

Line 188 in 64ec0b1

**kwargs: Any,

and treated the same as the create_patch variable:

GitPython/git/diff.py

Line 237 in 64ec0b1

if create_patch:

args.append(f"-U{lines_of_context}")

Is this something that could be added?
