Update meeting_hours.yaml for sp22

[ben9583]

Just leaving this here as a reminder as meeting times are still getting finalized but I'll prob update them myself once that's done.

Also it's looking like Web will be meeting at the same time as DDR and Finance is meeting once every two weeks, which may present some problems in ocflib so I'll create an issue there for that as well.

The issue of n-weekly meetings is probably gonna necessitate changes to schemas/meeting_hours.json too, so that's something to keep in mind.

(Possible) schedule copied from meeting 3 slides:

Meeting	Day	Time
Staff	Wednesday	8pm-9pm
BOD	Wednesday	7pm-8pm
Kubernetes	Saturday	11am-12pm
DDR	Saturday	12pm-1pm
Linux-Infra	Saturday	1pm-2pm
Web	Saturday	12pm-1pm
External	Saturday	2pm-3pm
Internal	Saturday	3pm-4pm
DeCal	Tuesday/Thursday	8pm-10pm
