- The user facing side of comments recently replaced `bio` with `expertise`.
- To remain consistent we replaced all the references of `bio` with `expertise` throughout the codebase.
- This includes a database column name changing migration, within the `members` table.
- Bumped up the comments-ui version to a new minor (0.10.x) as its a breaking change.
