Summary

Robot Framework files with extension .resource(link) is not currently associated with the language Robot Framework, so syntax highlighting when you view the file within a repository is just plain text.

Steps to reproduce

Open a file with extension ".resource" in any GitLab repository and observe that there is no syntax highlighting.

What is the current bug behavior?

No syntax highlighting

What is the expected correct behavior?

Should be syntax highlighted the same way as ".robot" files.

Possible fixes

Modify the RobotFramework field in vendor/languages.yml to associate ".resource" files with this language (in addition to ".robot").
