Migrate configs to TypeScript

[verytactical]

• jest.config.js
• jest-coverage.config.js
• setup-jest.js

Jest requires a ts-node to read configs from .ts, and it's a large dependency.

We have to migrate to vitest, and also port the @ton/test-utils library to work with vitest.

Typescript will cost us ts-node dependency - we can just enable typechecking on config files
