steering: Add Committee liaisons

Proposing Steering Committee liaisons for the following groups:
- Code of Conduct Committee (Tim)
- Security Response Committee (Stephen)

Choosing Tim and Stephen here, because:
- they're newly-appointed SC members with a lighter liaison load
- they have served on (or [have] operate[d] in) the respective
  committee's private spaces and are familiar with their processes
