Allow custom dotenv path for @remix-run/dev

[anqueue]

Currently, the only location a .env file can be for @remix-run/dev is the root directory of the project. Dotenv supports custom paths which is useful for any projects with shared .env files amongst other applications however Remix does not let you modify this.

My proposed change is to allow for a custom path option in remix.config.js so projects can take advantage of a shared .env instead of copy pasting or creating a symlink.

If you need to support different .env files, you can install dotenv-cli then update package.json to add dotenv -e path/to/.env remix dev

If you need any configuration beyond the default provided by Remix App Server, you should switch to the Express adapter, which gives you full control. I have a script that lets you eject from RAS to Express https://rmx.fyi/ejectras
