Add links to talks about the toolbar to the docs

[tim-schilling]

A good place to start would be the videos from searching djangotv.com: https://djangotv.com/search/?q=debug+toolbar

This will need a new page in the documentation for "Resources" or maybe "Show and Tell", though I'll defer to whoever implements it

@VeldaKiara did your talk get published?

Hey Tim, not yet.
They said they publish talks close to 2 months towards the next conference so probably end of this year I will have the recording

@VeldaKiara did your talk get published?

@tim-schilling happy to take this on.

I can assign it to myself once my membership request is approved.

I started with talks only, per the issue, but decided to expand into a broader "resources" section with tutorials and conference talks. This is my first-ever contribution to open-source code beyond correcting a typo here and there, so I welcome your feedback on everything from etiquette (should I have discussed my ideas before opening a PR?) to the quality of the proposed merge. Thank you.
