Docs: No info on environment variables in the /src folder

What is the improvement or update you wish to see?

Change this line in this page:

Config files like next.config.js and tsconfig.json should be inside the root directory, moving them to src won't work. Same goes for the public directory

To:

Config files like next.config.js and tsconfig.json, as well as environment variables, should be inside the root directory, moving them to src won't work. Same goes for the public directory

And add a note here:

Note: If you are using a /src folder, please note that Next.JS will load the .env files only from the parent folder and not from the /src folder.

Is there any context that might help us understand?

I've had this tiny issue that I didn't think of, but maybe one line in the documentation might help other people as well, since it's a small thing that is not mentioned: if you, by any chance, have environment variables in your /src folder, they're not gonna be read by the program. If you have them in the parent folder however, they will be read. Maybe it's not the most important problem around, but it would be great if it would be mentioned in the documentation somewhere (if not on both the Environment Variables page as well as the /src folder one).

Kind regards

Does the docs page already exist? Please link to it.
