update to use `dotenv` v17

[micalevisk]

Can you please update the project to rely on the latest version of dotenv (ie, 17)? not sure if that would be a major bump at dotenv-expand but I guess not -- see https://github.com/motdotla/dotenv/blob/master/CHANGELOG.md#1700-2025-06-27

dotenv-expand/package.json

Lines 53 to 55 in eac9220

	"dependencies": {
	"dotenv": "^16.4.5"
	}
