Product a report from `scope doctor run`

[noizwaves]

Now that scope doctor run output is dynamic, running the output through scope logs analyze requires some flags. It'd be great if a report could just be created if doctor run fails.

This PR will introduce that behavior:

When scope doctor run fails and a report location is present, a report will be generated and distributed.

The biggest changes here are:

• to expose more methods on ReportBuilder, enabling a report to be "built up" progressively
• update DefaultDoctorActionRun.run_action to accept a ReportBuilder, which is built up incrementally with each check and fix output
• make the report title an explicit argument when the report is created

Testing

Tested this manually by using an always failing check and a test GitHub repo report location.

A report location

After running bin/scope doctor run --only always-fail, this output was produced:

❯ bin/scope doctor run --only always-fail
ERROR Check failed, fix ran and failed, group: "always-fail", name: "exit 1"
Summary: 0 groups succeeded, 1 groups failed
