Cast `parseEnv` result to `Record<string, string>`

Casting is required instead of a simple annotation because the default return value `NodeJS.Dict<string>` sets the value to `string | undefined`. The `undefined` scenario is impossible with `parseEnv`'s current implementation, so to handle the the `undefined` case results in an untestable code branch.
