Line length change to 120

[Kludex]

What problem do you want to solve?

Hi there,

I mentioned this in the last meeting: I would like to propose an increase of line length in this repository because the code gets too polluted (not sure if it's the right word, but multiliny?).

Currently, it is set to 79 by pylint:

opentelemetry-python-contrib/.pylintrc

Lines 269 to 270 in 447aac2

	# Maximum number of characters on a single line.
	max-line-length=79

Describe the solution you'd like

Historically, in Python most projects have been using 88, till some years ago where people started using 120 (my guess is that the type system got too verbosed, and 120 is more acceptable).

In any case, I would like to propose we change it to 120.

The pros are: code far more readable.
The cons are: every PR will need a rebase.

We can add the commit to the .git-revs-file to not lose the history.

Would like to hear from other @open-telemetry/python-approvers. Beyond subjective perferences, the other con is that people with small screens or splits will have a harder time reading the code. But OTel is not unique here

Do you plan to use https://docs.astral.sh/ruff/settings/#format_skip-magic-trailing-comma to collapse multilines?
