Explain DevOps "index score" interpretation

See merge request gitlab-org/gitlab!23654

The meaning of the "index score" value in the DevOps Score feature
is not clear to everyone who reads the feature documentation. This
adds a sentence to explain one way it could be interpreted.

Refactor project milestone resources

See merge request gitlab-org/gitlab!23863

The fabricate method is not in use, and so it just adds unnecessary
complexity. This is why it is being removed.
The same applies to the description attribute.

Also, instead of having a title= method, better having it initiali-
zed with a default value so that it doesn't need to be provided
when creating the resource in the test file.

Finally, the test that uses the updated resource was updated to use
the default title.

Removed duplicate text
