Feature request: support javadoc in Ruby comments

[mikerobe]

Evidently javadoc-style comments (like @param, etc.) are commonly used in Ruby code. VS Code seems to parse it, in fact (if you hover over a ruby function with javadoc comments, VS Code parses the parameters, etc.)

When these comments are wrapped using the rewrap extension, they're not parsed properly (it just does paragraph wrapping).
