fix(env files): rename to --load-env-files (#10123)

Last change before releasing the minor. This wraps up the env files
feature started in #9961. To
recap on the naming decision a bit, we can't use just "--env-file"
because Node.js seems to parse it no matter what, and since Redwood's
flag operates on suffixes, Node throws a "not found" error. It also
seems to parse "--env-files", with an "s", which seems like a bug. I
opted for "--add-env-files" back when this flag only added additional
env vars, which didn't override existing ones. This is no longer the
case (they override), so I don't want to imply that they don't.
"--load-env-files" seems like the best alternative, and there's a
precedence in the work done in Node.js here which exposes a new
`loadEnvFile` function: nodejs/node#51476.

+  Fixes #9877. This PR adds CLI functionality to load more `.env` files via `NODE_ENV` and an `--load-env-files` flag.
   Env vars loaded via either of these methods override the values in `.env`:
 
   ```
   # Loads '.env.production', which overrides values in '.env'
   NODE_ENV=production yarn rw exec myScript
 
   # Load '.env.stripe' and '.env.nakama', which overrides values
-  yarn rw exec myScript --add-env-files stripe --add-env-files nakama
-  # Or you can specify the flag once:
-  yarn rw exec myScript --add-env-files stripe nakama
+  yarn rw exec myScript --load-env-files stripe nakama
+  # Or you can specify them individually:
+  yarn rw exec myScript --load-env-files stripe --load-env-files nakama
   ```
 
   Note that this feature is mainly for local scripting. Most deploy providers don't let you upload `.env` files (unless you're using baremetal) and usually have their own way of determining environments.
