Non-capture groups scoped incorrectly

[dsifford]

Hi there,

Great job on the grammar!

I noticed a small issue in the new scopes for RegExp...

https://github.com/Microsoft/TypeScript-TmLanguage/blob/cd202a57fd738d6d2c712c2ed63f5f41a11eb558/TypeScript.YAML-tmLanguage#L1958-L1963

Shouldn't line 1962 instead be punctuation.definition.group.non-capture.regexp?
