docs: add Rafael Belchior as a maintainer

[petermetz]

1. The MAINTAINERS.md file was updated with contact details
2. The CODEOWNERS file was updated so that in addition to the current
   code owners Rafael also has ownership of some of the sub-direcotires where
   he is the most active in terms of contributions.
3. We welcome Rafael to expand the scope of ownership on packages later
   as we are always looking to get more help with maintaining the code. :-)

Pull Request Requirements

• Rebased onto upstream/main branch and squashed into single commit to help maintainers review it more efficient and to avoid spaghetti git commit graphs that obfuscate which commit did exactly what change, when and, why.
• Have git sign off at the end of commit message to avoid being marked red. You can add -s flag when using git commit command. You may refer to this link for more information.
• Follow the Commit Linting specification. You may refer to this link for more information.

Character Limit

• Pull Request Title and Commit Subject must not exceed 72 characters (including spaces and special characters).
• Commit Message per line must not exceed 80 characters (including spaces and special characters).
