GIT is not supported

Error message

GIT is not supported

What it means

Raised by the Ruby gem installer when a gemfile block declares a `gem` with a `:git` option. Windmill's inline Ruby dependency management installs gems only from registered gem sources; git-sourced gems are rejected before installation since there is no git fetch/lock support in the worker's cache.

Solutions

1. Replace the git-sourced gem with a published version from a gem source
