Merge #2989

2989: vscode extension: migrate from any to unknown where possible r=Veetaha a=Veetaha

`unknown` type is the stricter version of `any` and it should always be prefered (like `const` over `let`).
It lets you assign any value to it, but doesn't let you carry out arbitrary operations on them without an explicit type check (like `typeof unknownValue === 'string'`).
