Handle JS block comments the same as SQL block comments

[nicklausroach]

YAML frontmatter should be handled the same way in Javascript as it is handled in SQL since the block comments are the same. Previously ABSQL attempted to parse the entire file as yaml and hit errors on backticks.

Thanks @nicklausroach - this looks good but can you please add a test and/or modify an existing sample file to capture the use case you have fixed?

[nicklausroach]

@chriscardillo good call. Added a a test that renders a simple JS file to make sure I didn't break that, and another test that renders a JS file with backticks. Happy to add more if that's helpful!

Changes made, tests added
