Prompt users to create a new team when adding a repository from an non-personal account

[gtsiolis]

Problem to solve

Currently, when going through /new prompt users to select a team after selecting a repository. We recently removed this prompt when a user is trying to add a repository from the personal account, see #6966.

However, a) creating a team for repositories from personal accounts does not sound helpful and b) users could go through adding a new project when viewing personal account projects which is the default dashboard page in / and /projects as we allow users to switch between personal accounts and orgs for GitHub, groups for GitLab, etc.

This is more relevant as adding a project you collaborate on with others on your personal account is not making it possible to invite other team members or allows others to request access to your personal account. 💡

Proposal

Revert the change in #6966 and prompt users to create a new team when adding a repository from an non-personal account.
