Describe the bug

Problem

It seems that the 'gleam' provider is trying to download an outdated/unavailable version of Gleam (0.39.0)

Temporary Remedy

In the nixpacks.toml [phases.install] (or equivalent json):

1. get Gleam from nixpkgs
2. use a newer nixpkgsArchive (example below was found here and built successfully on my system.
3. override the cmds, ensuring to not allow it to use the default Gleam install command.

Example:

[phases.install]
nixPkgs = ['gleam']
nixpkgsArchive = "1d9c2c9b3e71b9ee663d11c5d298727dace8d374"
cmds = []

To reproduce

Make a brand-new Gleam project (with probably any version of Gleam available at the moment)

build Gleam at least once (so there's a manifest.toml)

$ nixpacks build with project directory

It shows the error step in the planner, which fails when it runs: || install | cmds: sh /assets/get-gleam.sh 0.39.0 ||

Expected behavior

Expected

The auto-builder uses a functional Gleam version, if not the newest-stable one

Environment

OS: Pop_OS 22.04, x86_64
nixpacks version: 1.24.6
