[FIX] website_event_track: put partner_biography back on track proposal

Small oversight of #60847 where the "partner_biography" field was mistakenly
removed from the frontend track proposal form.

This commit simply re-introduces the field back into the form and saves it when
submitting the event.track proposal.

Task-2500455

closes odoo/odoo#69116
