Fix embedded Ruby's scope

[Arcanemagus]

It looks like here and here you are marking Ruby embedded in ERB files as the scope source.ruby instead of source.embedded.ruby as it should be. This is causing issues with linter-ruby and linter-rubocop attempting to lint these files since they think they are pure Ruby.

There is also an issue with linter-erb, which seems to be linting .html.erb files as if they were HTML.

[Arcanemagus]

linter-erb has not been updated to the current linter API as it seems to currently be abandoned, and thus couldn't possibly be the source of the errors as it can't have ever ran. The errors you show are from linter-ruby and are a result of this language package incorrectly marking the embedded Ruby code as regular Ruby code (as stated over in AtomLinter/linter-ruby#26 (comment)).

Makes sense.
