Move galaxy-importer from bleach to an alternative

Problem Description: bleach package is deprecated

Proposed Solution:

Now that bleach package is deprecated, check the behavior we’ve been expecting in https://github.com/ansible/galaxy-importer/blob/df274d4021de1314562400c3a4dd4eb657520a13/galaxy_importer/utils/markup.py#L145 for tags, attributes, and styles, and replicate with replacement, consider nh3 (ammonia) https://pypi.org/project/nh3/
