infra: reduce tsconfig complexity

[Shinigami92]

This PR turns around the tsconfig files. Previously we had one tsconfig.base file, from which the others extends (but not the normal tsconfig.json).

Now we have one tsconfig.json which serves as the root/base config for all others!

This tsconfig.json now only configures the minimum amount of base for all the other configs.

Then we have three specific configs:

build-types defines what is required to generate the files from src to dist/types
we need to have this because it declares the "include: [src]" which is needed to tell tsc it only takes files from this folder.
I looked already if there is a CLI flag for --include, but sadly no.

then we have two (right now mostly identically) configs for scripts and tests.
they differ in their "include"
We could discuss if we want to merge them into one file and just use one CI step to check tests and scripts folder, or we could just move the configs into there specific folders
The later option would result in VSCode would read them and process the configs for the folders

eslint now takes the tsconfig.json instead of its own lint.config
this results in that we now see even more lint errors that were previously hidden (see https://github.com/faker-js/faker/actions/runs/4822808872/jobs/8590495983?pr=2102)

Edit:

we now have one tsconfig.json which serves for all files and then one specific for the build process

I looked already if there is a CLI flag for --include, but sadly no.

It's literally the default argument.
tsc src/** is the same as only tsc with include: ["src/**"] in the tsconfig.json.

This explains why I did not found it 🤦
