Support for Vue

**Description of the issue**

Hi,

From the supported languages and frameworks I see that vue is supported for js/ts.
https://codeql.github.com/docs/codeql-overview/supported-languages-and-frameworks/
However, when I try to scan a repository which uses Vue.js for front end, it seems all .vue file are not scanned. Is vue actually supported?
Thank you!

Start with the supported languages and frameworks documentation and reproduce the report against a repository containing .vue files. Determine whether Vue files are expected to be scanned; done when the behavior is corrected or the support status and limitation are clearly documented.
