[enhancement]: Migrate type test to TSTyche

• There is no existing issue for my request.

Description

@foxriver76 I noticed the issue you opened in tsd repo. Just wanted to draw you attention that it can be solved by migrating type tests to different tool. I am the author of TSTyche (https://tstyche.org) and I would like to recommend using it instead of tsd.

Why?

• TSTyche has zero dependencies.
• the install size is only 219kB, because TSTyche will load TypeScript package you have already installed in the repo. (In contrary tsd ships its own copy of TypeScript and its install size currently is 48.0MB. Note that the install size of the latest TypeScript is only 20.9MB.)
• testing of specific version of TypeScript is as simple as: tstyche --target 4.8,latest
• and much more, like better performance or detail documentation: https://tstyche.org

How?

If it sounds interesting, I am more than happy to open a PR.

This issue received less feedback than the issue is was about to solve. (See tsdjs/tsd#221)

Oh well.. Great success! Whatever.. ;D
