[ruby/rdoc] Fixed CodeFence without blank lines

Currently a fenced code block needs a preceding blank line, it
should not be required, as:
https://github.github.com/gfm/#fenced-code-blocks
> A fenced code block may interrupt a paragraph, and does not
> require a blank line either before or after.

Just recommended:
https://docs.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks
> We recommend placing a blank line before and after code blocks
> to make the raw formatting easier to read.
