Description

gleam 1.10.0

When running gleam CLI under a proxy with a GLEAM_CACERTS_PATH wrongly set, the error is too ambiguous and is unclear that this is the problem.

What happens now:

> gleam run 
Resolving versions 
error: Dependency resolution failed

An error occurred while determining what dependency packages and versions should be downloaded. 
The error from the version resolver library was: 

Unable to determine package versions: file operation failed

Suggested:

> gleam run 
Resolving versions 
error: Dependency resolution failed

An error occurred while determining what dependency packages and versions should be downloaded. 
The error from the version resolver library was: 

Unable to determine package versions: certificate error
Hint: are you sure the certificates are correct?

or something along those lines

Contributor guide

Research direction
Find where 'file operation failed' is generated in the version resolution code and add a hint about checking GLEAM CACERTS PATH certificates.
