it looks good to me, but to understand the problem, is the problem that the default ruby version in appveyor is 3.2, and we need to set the ruby2.7 in front of the path to use it. As, I can see that ruby3.2 is installed in both ubuntu and windows appveyor images

It uses that line in Gemfile to recommend using specific ruby version, bundler fails otherwise. I can also remove that line and just update the ruby version in template to use the 3.2 since 2.7 is going to be deprecated soon.
