warning: Capturing the given block using Proc.new is deprecated; use &block instead

Hey folks,
I'm using ZAT and when launching my Sinatra instance using zat server I get the following output:

$ zat server
/var/lib/gems/2.7.0/gems/faraday-0.9.2/lib/faraday/options.rb:153: warning: Capturing the given block using Proc.new is deprecated; use `&block` instead

== Sinatra (v1.4.8) has taken the stage on 4567 for development with backup from Thin
Thin web server (v1.7.2 codename Bachmanity)
Maximum connections set to 1024
Listening on localhost:4567, CTRL+C to stop

As you can see in the output, the warning doesn't get in the way of the web server actually functioning. Just thought I would still report that in case it needs to be investigated.

As a note, I don't remember getting that error on macOS, if that helps troubleshooting.

My environment:

zat version # 3.8.1
ruby --version # ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]
gem --version # 3.1.2

The bug seems to be linked to Gem so perhaps I sould report that to them ?

I got the same problem, downgrading to ruby 2.4.10 remove the warning, not familiar with Ruby, but it's good if we can see an update on this

It looks like the issue with faraday was fixed here but ZAT still depends on 0.9.2. I'm just a user of this tool, but I may try to test using the newer faraday version and see what happens.

Can this get merged? It looks like this will fix and issue with ZAT that my team is using.

Zendesk likely abandoned ZAT and continue development in zcli, I already migrated two weeks ago, running well so far
