Build: Add SMASH docker image

[sgillespie]

Description

Partially fixes #1649. Adds a new image cardano-smash-server and a ghcr.io image registry. It should follow all of the conventions established in the cardano-db-sync image, which means it will accept variables for:

• NETWORK
• POSTGRES_USER
• POSTGRES_PASSWORD
• POSTGRES_HOST
• POSTGRES_PORT

Furthermore, we add the following variables:

• SMASH_USER
• SMASH_PASSWORD

To generate the credentials for basic authentication.

After this is merged, I will backport this to previous released 13.2.x and 13.1.x.

Thank you! 🙇 Do you plan to backport it to 13.1.0.0?

I have backported to 13.1.0.2: https://github.com/IntersectMBO/cardano-db-sync/pkgs/container/cardano-smash-server/201109389?tag=13.1.0.2

@sgillespie The link above points to 13.2.0.1, but we are interested in 13.1.0.2. I lost some time blindly following the link ^^
Anyways, the image for 13.1.0.2 exists and works with our db-sync default of 13.1.0.0.
And it was almost effortless to use it. Thank you.
