Add descriptions for Meeting Recordings

### Problem statement

Currently the Meeting Recordings are uploaded to YouTube with no description. Soon a link will be included to the relevant page on the website covered in each meeting. We should also look to expand upon what we are sharing.

### Proposed solution

Please come up with a summarizing paragraph for each session, to be included on YouTube as well as the dedicated webpage for Meeting Recordings. Maybe we create sub-pages with the recordings natively on the page (linked to YT). An expansion of this would be a simple list of instructions of how to follow along with the recorded session.

### Scope and impact

Let's create a system that is likely to support a wider reach for different users who join in the future, or those who may choose to go 'back to the beginning' to ensure understanding.
