feat(ng-dev): sort commits in release notes based on description

Commits within groups are currently sorted based on their commit
type. If types match, commits are displayed in the order they have
been extracted by `git log`. This is not ideal because f a custom
categorization method is specified though, commits could incorporate
an entry-point as prefix for commit descriptions.

The commits should be predictively sorted alphabetically if the types
match. This makes it easier to scroll through the release notes and
find commits.
