To reproduce:

Add a retired package to your gleam.toml, for example:

Expected:

My package to build/check successfully.

Experienced:

Failure of dependency resolution.

gleam check

Research direction
The issue requests modifying the dependency resolver to allow retired package versions while emitting a warning. The repository is written in Rust. Start by examining the dependency resolution logic in the 'src/hex resolver' or similar directory. Look for how retired packages are currently handled and where the resolution fails. Then, implement a change to permit retired versions but log a warning. Check the test suite for existing tests related to retirement and resolution. The maintainers may have discussions in linked issues or comments.
