Make it easy to see the map

Description

Create an easy method for people to publish map artifacts to some website.

A couple ideas:

• Provide easy configs to publish GitHub / GitLab pages if project doesn't use those features for anything else
  • GitHub Pages
  • GitLab Pages
• Provide modules for publishing to S3 Websites / Netlify / CloudFlare or other services like that
  • S3 Websites
  • Netlify
  • CloudFlare
• Allow hosting the maps on gitterra.com

Add documentation to the project, allow easy linking to a map as a badge or even including the map in README files.

Deploying the map to GitHub Pages can be relatively straightforward - I prototyped the workflow in the TestRepo:
https://github.com/GitTerraGame/TestRepo/blob/main/.github/workflows/gitterra.yml#L28-L51

It requires manual step to enable Action-based GitHub Pages deployments, but it is probably better for the safety of the repos so people don't accidentally override their main GitHub Pages site if they have one ;)

We can probably adjust the main GitTerra action to produce index.html instead of gitterrra.html file, after all, it is a most common default file convention.

@AlexanderChernyshev, @alexdruk, I documented how to deploy the map to GitHub and GitLab pages.

I feel that we explore the rest of the options in later.
