docs(config): Add scope-sorted example

[FoxxMD]

Description

Add an example configuration which details scope without grouping

• Same as basic example but sorts commit by sorted scope
• Defaults to "No Category" if no scope found on commit
• Adds a nested bullet for breaking change description

Motivation and Context

When a changelog has few commits per scope (like 1 or 2) the scopes in the "grouped" example make the changelog very busy. It's easier to read when commits are only grouped by type type and instead prefixed with the scope.

Additionally, the regular scoped example config doesn't handle commits without a scope.

Screenshots / Output (if appropriate):

Example output from my project:

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation (no code change)
• Refactor (refactoring production code)

I wasn't sure how to generate the example output for README without typing it out by hand so I left the raw/rendered details blank...hoping you can easily fill it in :)
