Merge branch 'blank-state' into 'master'

Updated blank state for environments and deployments

## What does this MR do?

Adds a designed blank state to environments and deployments.

@markpundsack do we want to hide the new environments when empty? Looks weird otherwise with the green button at the top.

## What are the relevant issue numbers?

Closes #18661 

## Screenshots (if relevant)
