bug: logs emitted on RPC failures when forking are not descriptive enough

Component

Forge

Describe the feature you would like

It's quite common in our codebase to experience CI failures related to RPC errors. For example:

Could not instantiate forked environment with fork url: ***

or

[FAIL. Reason: backend: failed while inspecting] 

Here are some logs for more context https://github.com/moonwell-fi/moonwell-contracts-v2/actions/runs/10927647686/job/30334305230?pr=350 https://github.com/moonwell-fi/moonwell-contracts-v2/actions/runs/10944099346/job/30385149157

It would be really great if the error messages from Forge could give us more details. We are not Rust engineers, so it's tough for us to figure out what's causing the issue.

Thank you!
