Update doc team meeting and remove doc/user-guides meeting

The current time schedule for the documentation team meeting is
not working for the team. This is the next best option with the
remaining available slots.

The doc/user-guides team meeting has also been removed in this
patch. The specialty teams were disbanded within the documentation
team and therefore the lead does not require a specific time to
meet any longer.

-  The OpenStack User Guides team holds one public meeting per month
-  on IRC. The meeting is set at 0630 UTC. We meet on the second
-  Thursday of the month.
-  Previous meetings were held at an APAC and US meeting time. Until
-  further updates, the User Guides team meeting will be held in a
-  time that aligns with APAC and European timezones. This best fits
-  our current team contributor locations.
