What is the purpose of this pull request? (put an "X" next to item)

[x] Documentation update

What changes did you make? (Give an overview)

From last month's TSC meeting, the TSC started using a calendar invite for meetings. When TSC members are added in the future, we should remember to add them to the calendar invite. This commit updates the guidelines for adding TSC members to include that reminder.

Is there anything you'd like reviewers to focus on?

Nothing in particular

LGTM, though technically this might need TSC approval since the Governance document is being modified...?

¯\_(ツ)_/¯ I suppose so. It does seem like it shouldn't be necessary for such a trivial addition though.

TSC Summary: This adds a line to the project governance documentation to indicate that new TSC members should be added to the Google Calendar invite.
TSC Question: (a) Should we add this line? (b) In the future, do trivial changes like this to the governance documentation need to be approved by the TSC?

I really don't think this needs to go to the TSC. We already decided we wanted to try using Google Calendar :)

I guess my take is, all Governance changes should require TSC approval, but maybe those guidelines shouldn't be in Governance since they're more of a practical checklist for what to do with new TSC members, rather than normative guidelines related to how the project should be run.

Going to go ahead and merge this given the response to this comment
