Documentation/CoC: Spell out the TAB role in enforcement decisions

Documentation/CoC: Spell out the TAB role in enforcement decisions

Updates the document to clearly describe the scope and role the TAB plays
in making decisions on unresolved violations. If and when the CoC has to
make a call on instituting a ban, it doesn't act without the TAB's approval
and only when the TAB approves it with 2/3 vote in favor of the measure.

These changes ensure that the TAB role and its oversight on CoC measures
is consistently described throughout the document.
