Unable to link specific repositories to projects

Issue overview

In our documentation we do not make it clear to users that in order to link a repository to your organisation or user owned project board the repository needs to have Issues enabled.

Content to update

In https://help.github.com/en/github/managing-your-work-on-github/linking-a-repository-to-a-project-board:

• Add a sentence "In order to link a repository to your organization or user owned project board the repository needs to have Issues enabled"
• We should really link to an article about issues being enabled, maybe https://docs.github.com/en/github/managing-your-work-on-github/disabling-issues?
