tsconfig conflicts with build

`shared-tsconfig` allow importing modules from `src` per module name.

https://github.com/kentcdodds/kcd-scripts/blob/5c6994534ab4438d4b7cf3ee9cea6981740f2298/shared-tsconfig.json#L13

The IDE picks this up and suggests using non-relative imports.

`kcd-scripts build` does not support the import from `baseUrl` and resulting build is corrupt.

### Suggested solution:

Remove the `baseURL`.

Open shared-tsconfig.json at line 13 and inspect how baseUrl enables non-relative imports. Remove baseUrl, then run kcd-scripts build and confirm the build no longer produces corrupt output.
