Upgrade to Mastodon v4.1.1

Minor update of container without any issue by means of Docker compose YAML infrastructure and automated Portainer GitOps workflow.
v4.1.1
The database health check in the Docker compose file has to be updated to look like, which are indeed the default values:

    healthcheck:
      test: ['CMD', 'pg_isready', '-U', 'mastodon', '-d', 'mastodon_production']

And an ENV varible has to be changed the following way:

RAILS_SERVE_STATIC_FILES=true
