Add charter about using pairing/mobbing

[romaricpascal]

What

Add a page in our team docs about our practices for collaborating to solve a problem on a synchronous call (pairing or mobbing), especially:

• different kinds of sessions we can do
• when to use them or not
• recommendations for structuring the sessions (length, breaks, things to provide ahead of time)
• reassurances about what happens in the sessions (it's OK if they feel slower, if you need to ask questions, if you have to drive but are not 100% sure about what to do...)

The page should probably live under 'How we work' as pairing/mobbing may happen across disciplines.

I can start with just a re-structuring of the points we discussed at dev catch-up and we can build upon those iteratively as we do more pairing/mobbing sessions.

Why

Pairing or mobbing can be a great way to work on a problem collaboratively. They're not suited to all situations and work better with a bit of a frame around them.

Following a discussion at Dev catch-up (internal link), we should document our preferences for this practice in the team docs.
