FIX Unknown alias: default (Psych::BadAlias)

[ps-ruby]

Ruby 3.0 comes with Psych 3, while Ruby 3.1 comes with Psych 4, which has a major breaking change.

1. The new YAML loading methods (Psych 4) do not load aliases unless they get the aliases: true argument.
2. The old YAML loading methods (Psych 3) do not support the aliases keyword.

This change is breaking the codebase while loading the database.yml and this PR handles that for ruby 3.1.x

Thanks for the PR @ps-ruby :)

@camertron Sorbet check is failing for lib/kuby/docker/remote_tags.rb. I tried auto-correct and it is making the changes shown below.

Should I make push the above changes?

[camertron]

@ps-ruby ah sorry about that. For some reason Sorbet isn't picking up that new class I added to Docker::Remote. I fixed it manually in master, so if you merge/rebase the tests should pass :)
