A new volume has been introduced for bundler dependencies. While PR rails/devcontainer#48 addresses the same issue, this implementation is simpler.

Steps to reproduce with Reinstalling Bundler Dependencies

• Run devcontainer --workspace-folder . up multiple times.

Expected behavior with Reinstalling Bundler Dependencies

• Stop the running Docker project.
• Run devcontainer --workspace-folder . up.
• Bundler should recognize that dependencies are already installed and not reinstall them.

Actual behavior with Reinstalling Bundler Dependencies
