Fixes #151

[plungingChode]

Environment key-value pairs, where the value contains a = character are now parsed correctly.

You can also achieve the same with:

const val = "x=x=y"
const [head, ...tail] = val.split("=")
console.log(head, tail.join("="))

Would you prefer this approach instead? If not, I will just accept your change as is

[plungingChode]

If you find your version more readable, I'll update the PR. It didn't really occur to me, to be honest.

[mishushakov]

I will accept and if I change my mind do the change myself. Thanks a lot for the contribution 🙏
