Passing CommOps seat to Alberto (bt0) for F29+

[Justin W. Flory]

Hi all, as planned before, my term on Mindshare expired with the Fedora
28 release cycle. Alberto Rodríguez Sánchez (bt0) will fill the CommOps
seat next.

I wanted to say thanks to everyone for the work we've started so far on
this committee and to welcome Alberto as the newest Mindshare
representative from the CommOps team.

Welcome Alberto! \o/

I opened a PR on the docs to make this official:
