Add the shorter option (-S) for --skip-ansible-lint

Issue: No JIRA issue opened for this.

Description

Provide the shorter alternative option (-S) for the --skip-ansible-lint option for better usability. -s (lowercase) was not chosen because it is used as the --strict option in ansible-lint.

Testing

Run ansible-content-parser with -S option and verify the report.txt file in the output directory does not contain outputs from ansible-lint. A Unit test is also included in this PR.

Steps to test

Build & install the updated code

Change to a work directory like /var/tmp

Download the PR branch:

git clone git@github.com:ansible/ansible-content-parser.git
cd ansible-content-parser/
git checkout 'ttakamiy/skip-ansible-lint-short-option'

Make sure python3 > 3.10 and create & activate venv

python3 -V
python3 -m venv venv
source venv/bin/activate

Upgrade pip and install dependencies

pip install --upgrade pip
pip install -e '.[test]'

Reactivate venv
```
deactivate
source venv/bin/activate
```
Run tox to build installable images (it also runs unit tests)
```
tox
```

Install the .whl file built by tox

pip install dist/ansible_content_parser-xxxxxxx-py3-none-any.whl

Reactivate venv
```
deactivate
source venv/bin/activate
```
Run ansible-content-parser with the --help option and verify the new -S option shows up
```
ansible-content-parser --help
```

Run ansible-content-parser with the -Soption against a simple sample project

ansible-content-parser -S https://github.com/ansible/ansible-tower-samples out

Check out/report.txt to verify there is no outputs from ansible-lint
```
cat out/report.txt
```
