WIP: Add Talk Submission Form

[jesscanady]

Currently the talk submission process is "ping someone you know and ask," which doesn't scale super well and also requires more effort than is necessary.

SO! Let's add a link to a form where folks can submit their talk ideas!

Where these go

As is current practice, the Board of Directors vets and schedules talk submissions. Currently interested speakers email/DM/carrier pigeon a board member they know directly. This form makes the process of submitting to the board that much simpler, and will hopefully reduce friction for new speaker submissions.

Long-Term

Using a Google form is fine for now, but eventually we'll want the submission process built into the application. We don't have a specific milestone for when that will become necessary, but PRs are always welcome for folks who want to give it a crack.

If you're interested in helping with this, hit us up in our slack. If you need an invite you can get yourself one here.

TODO

• Update the form to not hardcode a bunch of meeting dates.

I love both the idea behind this and the quick and dirty Google form solution. Could you please document in this PR who will be seeing these submissions?

Nice to have: success criteria upon which we move from the Google form to a feature of this app.

As usual, fantastic callouts @mikegee. I've updated the PR description with words that are maybe helpful here.
