Have tsc and eslint ignore the core/templates folder

[tordans]

We have a custom templates folder (blitz generate custom-templates). And we use npm run type-check with tsc --noEmit to check the types of all files in our projects.

Since we added the custom templates, those files show errors in tsc due to the needed template language.

I now excluded the templates folder in my tsconfig.json with "exclude": ["node_modules", "**/*.e2e.ts", "cypress", "src/core/templates"],.

Does anyone see an downside to this? And if not, would a PR to add a hint on the docs page be welcome?

Update 2022-01-11: The same is true for eslint. I had to update my package.json like this so there is no error.

"lint": "eslint --ignore-pattern \"src/core/templates/*\" --ignore-path .gitignore --ext .js,.ts,.tsx .",

In case someone searched for the error message, here it is:

/MY_PATH/src/core/templates/page/index.tsx
  0:0  error  Parsing error: ESLint was configured to run on `<tsconfigRootDir>/src/core/templates/page/index.tsx` using `parserOptions.project`: <tsconfigRootDir>/../../../../MY_PATH/tsconfig.json
However, that TSConfig does not include this file. Either:
- Change ESLint's list of included files to not include this file
- Change that TSConfig to include this file
- Create a new TSConfig that includes this file and include it in your parserOptions.project
See the typescript-eslint docs for more info: https://typescript-eslint.io/linting/troubleshooting##i-get-errors-telling-me-eslint-was-configured-to-run--however-that-tsconfig-does-not--none-of-those-tsconfigs-include-this-file

The eslint docs suggest different approached. The one using the separate package.json entry did not work. The one above does. https://eslint.org/docs/latest/user-guide/configuring/ignoring-code#the-eslintignore-file

I think that should be hinted on the the docs as well. I can make a PR if this is desireable.
