Create Contractor compliance policy

[KerrieJarman]

This is a policy to regulate how we deal with contractors

Is this at all related to the governance working group?

No it is a policy that should have been in place when we first brought on paid contractors

Edit: After further internal discussion, the use of "unfairly" is enough to explain the difference here.

~~I'd like to add a recommendation that the CoE is updated so there is not a conflict in this. The CoE states:~~

~~> 5.1 A WCA Staff member must not use their power within the organization/community to unfairly benefit an individual or group, including, but not limited to:~~ ~~>> 5.1.1 Monetary benefit~~

~~Although I acknowledge that the Motions are above the CoE per 21.2024.1 - WCA Documents, it might be good to address this explicitly as an exception to avoid confusion since this PR also uses the term "monetary benefit" explicitly.~~
