Pass id to volunteer contact form

[bethanyaconnor]

See Slack thread

The contact form started returning a 400 error on submit, likely as a result of replacing Google Maps with Mapbox. The request wasn't sending the volunteer ID, which was required.

This fix tried to emulate the removed code, which was setting a hidden form field. It isn't a pretty fix, but I tested locally and I can submit the form. Definitely open to suggestions for improvements.
