Error installing mgold/elm-date-format

[hpate-omicron]

First, thank you for the library, it has made it way easier to handle private Elm packages!

I noticed this on our CI when it updated to v1.3.0, it didn't happen previously on v1.2.0:

Short version:

elm-github-install install

Minimal case:

{
    "version": "1.0.0",
    "dependencies": {
        "mgold/elm-date-format": "1.4.0 <= v < 2.0.0"
    },
    "elm-version": "0.18.0 <= v < 0.19.0"
}

I looked through the elm-date-format repo and I think it may be that the 0.1.0 version is tagged as 0.1 in the Github release - https://github.com/mgold/elm-date-format/releases?after=0.1.1

Here's the output from v1.2.0:

First, thank you for the library, it has made it way easier to handle private Elm packages!

Glad to hear it! 🎉

Nice catch and I really appreciate the minimal case 👍 😄

Fixed in 1.4.0 - https://github.com/gdotdesign/elm-github-install/releases/tag/v1.4.0
