Adding TMRG discussion Guidelines

Why is this change being made?

Creating an MR to address this issueto create a set of guidelines regarding political discussions within TMRGS.

Some TMRGs will have to have what could be regarded as political discussions as the nature of enabling and empowering that group will require this. Which could be discussing legislation, policies or systemic issues with politics, legal or other institutions.

This provides some guidelines on where this could be appropriate and where we should not be discussing politics in TMRGs.

Before merging, we should discuss this MR with the TMRG Leads and Co-Leads and the DIB Advisory Group.
