Decide what to do with Working Groups

As discussed in the next meeting, the next step is to send an email blast to folks who are part of Working Groups (and likely other Launching Pad subteams) to identify groups/teams that are "clearly" in one of two states:

1. Generally idle, and should be archived
2. Significantly overlapping with existing Rust teams, and should either be merged, or made a subteam of an existing team

This leaves out teams that have an outcome other than the two listed above, which we can handle once we have the greater list pared down.

Action is on @jamesmunns to:

• Create a list of teams and contact info for members of those teams
• Draft the email, probably check with council for review
• Send email process responses
• Close/merge teams that self-identify to those categories
• Update the list of remaining pending teams

Noting that I'm starting this as part of the "general check" in #118, rather than doing it by email.

There will probably be a separate discussion of what to do with working groups that are still active.
