Add contact info for getting API keys

Here is a simple thing to add to the About pop-up and here is a proposed About update:

A free and open vulnerabilities database and the packages they impact. And the tools to aggregate and correlate these vulnerabilities.

• Sponsored by NLnet https://nlnet.nl/project/vulnerabilitydatabase/ for https://www.aboutcode.org/
• Chat at https://gitter.im/aboutcode-org/vulnerablecode
• Docs at https://vulnerablecode.readthedocs.org/
• Source code and issues at https://github.com/nexB/vulnerablecode

If you want to try the JSON REST API, please send a note to info@nexb.com to request an API key for testing.
