Rely on TypeScript 4.7 and update integration + tests

* Only test against TypeScript 4.7

* Move type definitions to entrypoints/

Only TS 4.7 will resolve them now, but it's cleaner.

* Use @sindresorhus/tsconfig

* Fix test TypeScript files, make compilable and lintable

* Use tsc directly, instead of tsd

* Add *.cts versions of type tests

* Reorganize type tests

* Use tsc directly, avoid npx, print actual version

Somehow `npx tsc` was pointing at an older version. Possibly the binstubs are corrupted in CI… somehow.

 AVA comes bundled with a TypeScript definition file. This allows developers to leverage TypeScript for writing tests.
 
-This guide assumes you've already set up TypeScript for your project. Note that AVA's definition expects at least version 4.4.
