🌱 Improve printing options (#1584)

When print options, there are two sections: "Scorecard options:" and
"Event / repo information:". However, the headers of these sections have
the same format as the options themselves (name followed by ":"). So I
initially failed to identify they were just headers, and thought they
were actual options that were empty.

I think indenting entries inside each section helps avoid this
confusion.

Before:

```console
Scorecard options:
Ref: HEAD
Repository: ossf/scorecard
Local:
Format: sarif
Policy file: /policy.yml

Event / repo information:
Event file: /testdata/fork.json
Event name: branch_protection_rule
Fork repository: true
Private repository: true
Publication enabled: false
Default branch: main
```

After:

```console
Scorecard options:
  Ref: HEAD
  Repository: ossf/scorecard
  Local:
  Format: sarif
  Policy file: /policy.yml

Event / repo information:
  Event file: /testdata/fork.json
  Event name: branch_protection_rule
  Fork repository: true
  Private repository: true
  Publication enabled: false
  Default branch: main
```
