Use recommended filenames for compose config and binary

[dvdksn]

What's being changed:

The recommended filename for Compose files is compose.yaml, and compose is now invoked as a subcommand to the main docker CLI, as opposed to a separate docker-compose binary.

Type of change:

• Documentation updates (non-breaking change to fix/update documentation)
• Website updates (non-breaking change to update main page, company pages, pricing, etc)
• Content updates – blog, podcast (non-breaking change to add/update content)
• Bug fix (non-breaking change to fixes an issue with the site)
• Feature or enhancements (non-breaking change to add functionality)

How Has This Been Tested?

• GitHub action – automated build completed without errors
• Local build - the site works as expected when running yarn start

note, you can run yarn verify-links to test site links locally
