(DOCSP-44543): Add support for missing Drivers languages

[dacharyc]

• Still need to add support for:
  • [ ] Ruby block comments: https://docs.ruby-lang.org/en/master/syntax/comments_rdoc.html After speaking with Kay, that comment syntax is mainly used for doc comments and we don't need to support it for Bluehawk purposes
  • Decide whether/how to support both PHP comment syntax (// and #)
  • [ ] ipynb - is this possible? : ipynb isn't just text - I don't think we can use Bluehawk to work with it

Jira ticket link: DOCSP-44543

Content of ticket, since this is an open source tool that theoretically anyone could use...

Bluehawk does not currently support parsing files in all of the Drivers language types.

Add support to the rstLanguageMap for missing Drivers programming languages:

• C
• Go
• PHP
• Python
• Ruby
• Rust
• Scala

Add tests for files in each language.

Confirm our handling of comment syntax covers all of these languages, or put in separate tickets to update Bluehawk to accommodate anything that's not supported.

As a stretch goal, support .ipynb files so we can use Bluehawk to copy Jupyter notebooks between repos.
