(low priority) Ruby syntax highlighting issue for regex literals with ! - or + operators

Steps to Reproduce:

audience = "world"
thing = ! /hello #{audience}/
puts thing 
#>>> true 

The syntax highlighting for /hello #{audience}/ is screwed up. The problem also exists if the - or + operators are used, however the ~ operator has the correct highlighting.

Solution:

This is a pretty small problem, so mentioning this in the ruby.tmLanguage.json is probably sufficient.
I'm somewhat familiar with language files so I might be able to add a fix and create a pull request in the next few weeks.
