Feature request: add patches from https://github.com/katjanakosic/vscode-json5

[MarioVilas]

This repo has a few improvements, most importantly (to me at least, and I think for other people as well) the possibility of highlighting keys with a different color than string values.

I'm currently working on a project where all keys and values in our JSON5 files are strings, and it's pretty much like working with no syntax highlighting at all...
