Make Past Talks Pages Dynamic

[Nealium104]

Next.js has the ability to make dynamic pages and display routes dynamically. We'll make a folder of each Past Talk with a date such as 'Oct2023'. That folder should contain an array of objects to be passed into a new component for rendering on each route. This should make it easier to maintain as more talks are added. After each talk, it should be as simple as making a new folder, and then copy-pasting an object. Should be just a rework of existing material with the addition of 3-4 components.

Addressed by #48, with a JSON implementation.
