Update the json-schema for `tsconfig.json` with TSTL

[Toliak]

Description
I'm very frustrated when I'm trying to setup tstl section in tsconfig.json and my IDE hints me nothing.

I would like to suggest to provide the json-schema for tsconfig.json with tstl section.

The solution
I have already made the described json-schema :)

To use it insert

"$schema": "https://raw.githubusercontent.com/mtasa-typescript/mtasa-lua-utils/feature/toolchain/tstl-tsconfig.schema.json"

at the top of your tsconfig.json file.

In VSCode:

In WebStorm:

Are you interested in this feature? If the answer is positive, I could create Merge Request with the schema file (just let me know, where to place it)

Good idea, do you think you can generate the schema from: https://github.com/TypeScriptToLua/TypeScriptToLua/blob/master/src/CompilerOptions.ts

That way, we could make the generation of the schema part of our build/release script and wouldn't have to maintain it manually.

Edit: Or maybe generate it from the website? But I would also be fine with a manual schema.

Actually, we already have a custom schema. It is located in our vscode plugin, so you might want to make a PR there instead:

About auto-generating schema: the first google result redirects me to the typescript-json-schema package.

However, I'm not fully understood, how the pipeline will look like. In my head it's something like:

1. On commit into master branch of the typescript-to-lua: github action (or something else) generates the updated schema
2. The updated schema is being commited (or Merge Requested) into this repo (vscode-typescript-to-lua)

Maybe mention the schema somewhere in documentation, because, when I searched, I haven't find anything :c

I will make the Merge Request with manually changed schema in a few minutes

Auto-generating is not a priority, I just thought it would be cool. So, that's something we might want to look in the future, but a manual schema is totally fine for now.
Also, not sure if the schema should be part of the main repo or if we should just keep it in the vscode plugin.

To be honest I didn't even know the vscode plugin had this capability until 5min ago :D
Please don't hesitate to open another PR for the website(https://typescripttolua.github.io/docs/configuration) that links the updated schema from this repo.
