I ran into issues when copy-pasting the docker-compose.yml contents from
https://docs.gitea.io/en-us/install-with-docker/ - specifically the part
about adding PostgreSQL to the YAML file; I tried manually adding the
diffs by removing the `+` at the beginning of lines, and the resulting
YAML was unparsable.
This forces the indentation to be consistent across all places where
YAML is used.
