System

• OS: Linux, Fedora 37
• ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux]
• bundle -v: Bundler version 2.3.26
• bundle info arduino_ci: link to git clone (checked out 2021-02-15_rescue branch).

Issue Summary

The readme file contains the following suggested command

$ bundle install --path vendor/bundle   # adds packages to local library

However running it generates a deprecated warning:

[DEPRECATED] The `--path` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local path 'vendor/bundle'`, and stop using this flag

I have an old branch that should fix this as far as I can see. I just rebased it on top of latest master (it was just two commits behind).
