This PR does the following:

1. Break out the monolithic ruleset.yaml into an organized directory of smaller rulesets.

rulesets
├── ca
│  └── _multi-metroland-media-group.yaml
├── ch
│  └── nzz-ch.yaml
├── de
│  └── tagesspiegel-de.yaml
├── gb
│  └── ft-com.yaml
└── us
   ├── _multi-conde-nast.yaml
   ├── americanbanker-com.yaml
   ├── medium-com.yaml
   ├── nytimes-com.yaml
   ├── usatoday-com.yaml
   └── washingtonpost-com.yaml

Create a CLI option --merge-ruleset and --merge-ruleset-gzip that optionally merges the rulesets into a single file for release.

I'm not familiar enough with Github CI/CD and goreleaser to make changes with the releaser, but ideally the ruleset.yaml should be distributed with the release files.

Something like this in .github/workflows/release-binaries.yaml

        name: Build rulesets for release
        run: |
          go run cmd/main.go --ruleset "./rulesets" --merge-rulesets --merge-rulesets-output "ruleset.yaml"
