update bios

[techieshark]

Bio, picture, contact info, and social media links should be updated for City Manager, Mayor, and Council.

Implementation notes:

• a separate issue is making it easier for this to happen again (by city staff). Ideally we'd have an API for this info but currently we can't get enough of it out of Legistar and as there is no other alternative, we might setup something simple involving json files on github. I played around with a simple tool for collecting data (which for the moment requires copying and pasting), using json-editor from @jdorn.

Thanks to some work by @wendyfongsf (using the editor above to create the contents of people.js) and some new code in this commit, this issue will be resolved after @buckleytom merges #26.
