Add B3IT to "approved reviewers"

[sreichel]

@colinmollenhour i'd suggest to give @Hanmac and @theroch permissions for green flag reviews - if you like.

Thanks for the nomination, @sreichel. No objections from me, and I see @addison74 agrees.

I've sent invites for the LTS Writers group for both of you, @Hanmac and @theroch! Thanks for your past and continued support!
