Fix bundle install commands

About

This MR fixes a Docker build issue where deprecated bundle commands were used. As we didn't pin the version of bundler, a new major version of the gem was published on December 3rd 2025, and the subsequent MRs accidentally used this new version.

This MR does the following:

• Pin bundler to the version the Gemfile.lock was built with to 2.4.22
• Fix the commands to not use the deprecated parameters to eventually prepare for a new version of bundler just in case.

As a follow up, we can upgrade the version of bundler points to.

Testing evidence

I was able to locally test those changes.
