Revise Participating Institutions page

[stephaniesimms]

• remove "No affiliation" from the list (see screenshot)
• default sorting should be alphabetical (this should be addressed by Roadmap issue)
• add introductory text below page header: "Participating institutions/organizations can configure the tool to point to their resources and services, provide customized help, and provide suggested answers to the questions asked by funding agencies. DMPTool users affiliated with partner institutions can login with their own institutional accounts. For more information visit the About page."
• make About a hyperlink

Participating institutions/organizations can configure the tool to point to their resources and services, provide customized help, and provide suggested answers to the questions asked by funding agencies. DMPTool users affiliated with participating institutions can login with their own institutional accounts. For more information visit the About page
