[IMP] events: update track and manage talks

[ksc-odoo]

PROJECT TASK: https://www.odoo.com/web#id=3915122&cids=3&menu_id=4720&action=333&active_id=3835&model=project.task&view_type=form

This PR discuss what the Talks, Talk Proposals, and Agenda event website pages entail -- and how to utilize and navigate them.
This is meant as a supplemental PR to the 'Create event tracks' doc...which is focused more on the backend elements and how to create tracks for an event.

This PR should be published/merged after the 'event_tracks' PR
That's why there is likely going to be continued Build Errors -- because that 'event_tracks' doc is referenced in the seealso at the end.

I worked off the original RST file name so that I didn't ruin any potential reference links that could be lingering elsewhere...

Hi @ksc-odoo

Looks good, I like how you focused the content to be more specific to talks instead of the other topics that were included in the previous iteration (Attendees, LGR, etc.)

I just had a few comments below for you to look at. Once they're addressed to your liking feel free to move on to tech review.

Cheers!
