Update latest image tag to new ubuntu (22 or above)

[cb-krishnapatel]

What would you like added?

I see the ubuntu 20 support has officially ended and multiple vendors are removing support for ubuntu 20. Can we plan to move latest tag in the image to ubuntu 22 or higher? Github officially has moved its ubuntu-latest to 24.

Why is this needed?

Ubuntu 20 support has officially ended. Various vendors like hashicorp are not supporting installation on ubuntu 20.

Additional context

I am aware that we can update the images to a specific OS as we want. Even i have updated the images at my end. Just that this request is for large-scale audience who might face this, and also its the next step.
