Fix integration tests failing on Debian Buster EOL (#1918)

[JamesIves]

This pull request updates the integration workflow configuration to use newer versions of the Node and Ruby containers, ensuring compatibility with current dependencies and improved security.

Container version upgrades:

• Updated the integration-cross-repo-push job to use the node:22 container instead of node:16.13 in .github/workflows/integration.yml.
• Updated the integration-checkout-v2 job to use the ruby:3.3 container instead of ruby:2.6 in .github/workflows/integration.yml.
