JSON LSP complaining about `perlnavigator.perlcriticMessageFormat` not being allowed

[stefanhaerter]

I use neovim with coc.nvim, and when I'm in my coc-settings.json, the JSON LSP complains about perlnavigator.perlcriticMessageFormat:

I copied the example you kindly provided here, and it works just fine - only the LSP complains.

I couldn't really understand why, as I checked these three files and the key is present in every single one of them:

• browser-ext/src/web-types.ts
• server/src/server.ts
• server/src/types.ts

So no actual problem, but I thought I might let you know just in case that this points to something hidden.
