Improve code style of GitHub Actions workflow files

[ygrishajev]

Is your feature request related to a problem? Please describe.

The current state of workflow files makes it harder to consume. Some steps are missing from the eyesight due to formatting or proper declarations.

Describe the solution you'd like

Format workflow files in all akash projects:

• distinguish steps better with spacing
• make sure every stem has a proper human readable naming

Describe alternatives you've considered

It's a simple improvement making the code cleaner. Alternative solutions are not applicable here as it's not related to functionality itself.
