Suggestion: allow multiple .env files to be loaded

[ptrxyz]

I find myself quite often dealing with projects that have several .env files, i.e. something like .env for general settings and .env.production/.env.development/.env.build which overwrite settings from .env for certain scenarios.

Currently my way to work with this is to set dotenv-load (to load the .env globally) and then manually add source .env.{{mode}} && ... to every command.
I wonder if we could allow to load multiple dotenv files in order, maybe through having dotenv-filename being a list of items or a colon-separated string?

Something like this maybe:

dotenv-filename := [".env1", ".env2"]
dotenv-filename := ".env1:.env2"

this would require the files to all be in the same directory, so maybe we simply have a list of paths (["./packages/ui/.env", "./packages/backend/.env"]?
