Fixed Logger flag and added auto-upstream feature

[Seif-Mamdouh]

Description

In this PR I added a feature and fixed a bug

Bugs

• polished the logger flag functionality in ./cli/config_handler.py that was caused by rebasing in previous PR's

New Features:

• added a feature to ./cli/gen_ai_commit_message_handler.py to handle the case if the user tries to auto commit on a branch that hasn't been upstreamed with main yet!

Test Plan

--logger, -l

long version

git_ai_commit config --logger true

short version

git_ai_commit config -l true

expected output:

Logger enabled

Testing for false

long version

git_ai_commit config --logger false

short version

git_ai_commit config -l false

expected output:

Logger disabled

Handle the case where user's current branch has not upstreamed yet

git checkout -b <your-branch-name>

pip3 install . && pre-commit install && pre-commit autoupdate

git add .

git_ai_commit_message

expected_output:

No upstream branch found. Setting upstream for branch <your-branch-anme >
git push ---set-upstream origin <your-branch-anme >
