Merge both TypeScript configs

There was no strong reason for maintaining project references,
especially because some of the tooling doesn't support it. By using a
single config we make TypeScript checks faster and tools aren't running
into problems.

- TypeScript ESLint: typescript-eslint/typescript-eslint#2094
- eslint-import-resolver-typescript: typescript-eslint/typescript-eslint#2094
- Vitest: vitest-dev/vitest#3752
- Remix also didn't work, but I wasn't able to find the issue, probablt
  esbuild

So that's at least 4 tools not working. 😄
