Add test-types script back

[jablko]

I ran into an issue with test-types which this PR solves by adding "types": [] -> **/tsconfig.json. If it was the issue with test-types, perhaps it can be restored -> the CI?

#1179 temporarily moved test-types -> its own types.yml workflow, suggesting it be moved back -> test once it's running stably:

This will be a temporary change until we see dtslint running stably, then we can move test-types back under the test command.

types.yml was subsequently eliminated in #1338.

The issue I encountered was dtslint implicitly including and checking every node_modules/@types declaration:

Error: Errors in [email protected] for external dependencies:
../../../node_modules/@types/prettier/index.d.ts(537,14): error TS2456: Type alias 'Doc' circularly references itself.

    at /home/nottheoilrig/mdx/node_modules/dtslint/bin/index.js:206:19
    at Generator.next (<anonymous>)
    at fulfilled (/home/nottheoilrig/mdx/node_modules/dtslint/bin/index.js:6:58)

This PR solves that by adding "types": [] -> **/tsconfig.json:

$ for tsconfig in $(git ls-files '**/tsconfig.json'); do
  git show ":$tsconfig" | jq '.compilerOptions.types = []' > "$tsconfig"
done

This will still type check our explicit node_modules/@types dependencies, however it will no longer implicitly include every node_modules/@types declaration.

Concurrent dtslint invocations were trampling each other installing TypeScript versions ... At least I think that's what was happening here -- and here ... Perhaps here too ...

[ChristianMurphy]

Sounds alright to me.
Thoughts on this approach @JounQin?

[JounQin]

I'm not sure, personally I'd prefer something like Expect type utility for types.test.ts, and run tsc --noEmit for type checking for all .ts related files.

But for multiple ts versions, dtslint maybe better.

However, I don't think targeting multiple ts versions are worth unless we're not going to always follow latest TypeScript.

[jablko]

@JounQin I think most of this change applies equally to tsc --noEmit and dtslint: Without "types": [] we'll implicitly include every node_modules/@types declaration in either case, I think?

Can we land this, and roll back the lerna --concurrency 1 option if/when we drop dtslint?

[JounQin]

OK, whether to drop dtslint can be discussed later, let's fix current issues first.
