[FEATURE] Fewer comments in the generated CODEOWNERS file

[gustavkj]

Is your feature request related to a problem? Please describe.
Right now, a comment (e.g. # Rule extracted from dir1/CODEOWNERS) is added before every rule in the generated CODEOWNERS file. This is quite noisy.

# Rule extracted from dir1/CODEOWNERS
/dir1/**/README.md @miny
# Rule extracted from dir1/CODEOWNERS
/dir1/README.md @moe
# Rule extracted from dir2/CODEOWNERS
/dir2/**/*.ts @moe
# Rule extracted from dir2/CODEOWNERS
/dir2/dir3/*.ts @miny

Describe the solution you'd like
I suggest having one comment before each collection or rules from each file.

The example above would then be:

# Rule(s) extracted from dir1/CODEOWNERS
/dir1/**/README.md @miny
/dir1/README.md @moe
# Rule(s) extracted from dir2/CODEOWNERS
/dir2/**/*.ts @moe
/dir2/dir3/*.ts @miny

Describe alternatives you've considered
I haven't considered any other solutions for this.

Additional context
I can help fix this. But adding issue for discussion and track keeping.

good idea @gustavkj we didn't do it because we have very big nested codeowners and ppl was losing track of what was going on. I will consider this added as a feature in the configuration, thoughts?
groupSourceComments: true or something to that effect.

A config option sounds good!
