Describe the issue:
Whenever I open or create a JSON file, Positron thinks it is as a renv lockfile. This happens when I open an existing file, or create a new file with a .json extension.
I also noticed there is no plain JSON file type as there is in VS Code. Or at least, it thinks plain JSON is an renv lock file.
This is a screenshot from Positron:
And from VS Code:
Hmmmm, I guess this is happening because of how we do this:

This is how we add the syntax highlighting for renv.lock, but we have not ended up in a great place.
