Add project: use richer list display for organization/team

[humitos]

We want to use a richer list display in the first step on Read the Docs for Business when adding a new project. There are some extra information we want to display in the list in a nicer way:

• status of the organization (e.g. disabled)
• Authentication backend (e.g. GitHub SSO, Google SSO, SAML, etc)
• ... maybe more

There are some extra context about this issue in other conversations:

• Add project: don't show VCS SSO organization if the user is not the owner #466
• Add project: don't show disabled organizations #467
