[Bug] Dependency issue with Ruby 3.4+ (missing erb gem)

[this-is-varunxyz]

While setting up the local development environment on a system with a recent Ruby version (e.g., Ruby 3.4+), the build fails with a LoadError.

The cause is that erb is now a 'default gem' and is no longer part of Ruby's bundled standard library. It must be explicitly included as a dependency for projects using Bundler.

Adding gem 'erb' to the Gemfile resolves the issue.
