fix: address removed attributes on team table

[JayRovacsek]

As per #530 the team table is broken

Please note that I recognise the removal of these fields is a worst-case scenario for consumers of this field. I have not deeply investigated if these fields could be reimplemented, the changelog upstream that introduced the issue only removes the fields and there may be other graph entities that can be hydrated from that would re-enable these fields in the github_team table. At current time, it appears all calls to github_team are failing due to this however.

Utilised test sql is:

select
    combined_slug,
    created_at,
    description,
    id,
    name,
    organization,
    parent_team,
    privacy,
    slug,
    updated_at
from
    github_team
where organization = 'acme'
limit 10

Results before applying the changes in this PR:

Error: github: Field 'discussionsUrl' doesn't exist on type 'Team' (SQLSTATE HV000)
