Please remove Build Azure Virtual Machine Image from GitHub Marketplace

[jsoref]

Build Azure Virtual Machine Image appears prominently in the marketplace:

https://github.com/marketplace?query=Azure+Virtual&type=actions

There's no need to list an action on the marketplace unless you're:

• Supporting it
• Looking for more consumers

Anyone can use any public github.com repository as an action source regardless of whether it is published to the marketplace.

This action isn't usable:

• It's using node12 which hasn't been supported since August 2023:
  

  build-vm-image/action.yml

  Line 62 in 49519e8

  using: 'node12'

There haven't been any commits since 2022: https://github.com/Azure/build-vm-image/commits/master/

There's no reason to continue advertising an action that won't work.
