--env reports dotenv files as not found when the dotenv file has a syntax error, despite reading from it

[KlaasSkelteAtEnatom]

Version: Deno 1.43.1

To reproduce:
.env

VALID=valid
INVALID=c:\path

test.ts

console.log(Deno.env.get("VALID"));
console.log(Deno.env.get("INVALID"));

Run with deno -A --env test.ts

Output:

Warning The `--env` flag was used, but the dotenv file '.env' was not found.
valid
undefined

This is an improvement over older versions, because it at least loads something. Still, I'd rather have deno not show the warning, because it is factually wrong.
