Initial slide fixes for ICCS summer school 24

[ma595]

This PR fixes minimal aspects of the workshop's accompanying slides in readiness for the 2024 edition of the ICCS summer school. There is scope to add more.

I have added Surbhi and I as additional authors. I would like to emphasise that we are teaching the session, if possible. @jatkinson1000 do you you have any formatting suggestions?

• Fix the parameter update rule. See https://en.wikipedia.org/wiki/Stochastic_gradient_descent
• Various spelling and style changes
• Modify names of presenters, and acknowledge Jim and Jack.
• Create 'material' slide that points to github link and cites Jack and Jim's code and JOSE paper.
• Amend contact with two additional columns.

Closes part of #61

All seem sensible.

One comment is to drop the 'AZ' from @jdenholm's affiliation and make him UoC or something, as I know they are picky about what their name appears on.

Any suggestions on how to make the actual speakers' names stand out on the title page? i.e. with some quarto emphasis effect? I wasn't able to figure this out quickly.

[jatkinson1000]

All good from me.

Regarding the formatting question - my suggestion would be to put yourself and Surbhi on the title slide to make it clear who is teaching.

What you could do is put a note on the subsequent slide with license and repo links etc to say it is based on the workshop developed by Jim and I. If you could also add a citation to the JOSE paper there that would be wonderful.

I will approve the PR now, as this is not a critical blocker, but that change would be appreciated :)

I'll attempt to address Jack's comments first.
