Update GitLab for Nonprofit handbook page

GitLab is a single platform for project management, collaboration, source control management, git, automation, security, and much more. Because it is easy to use, flexible, and all in one place, it is the best choice for nonprofits to scale their work. The GitLab for Nonprofits Program gives free licenses of GitLab to registered nonprofit organizations.

Nonprofits accepted into the program will be provided a free Ultimate license for one year (SaaS or self-managed) for up to 20 seats. Additional seats may be requested although they may not be granted.
