Intro single-cell training fixes from June 2023

[sjspielman]

Post anything we need to fix for scIntro here!

Should we add a pronouns bullet to the "what is your name" slide? (Actual/serious comment)

Now that I wrote that, I feel a need to also suggest "what is your favorite color" and "what is the airspeed velocity of an unladen swallow?" (Less serious comment)

Slide 13 for intro to R slide deck needs an updated screenshot with .Rmd not .md extensions.

Modify the way we refer to the family of write functions, as the underscore is in the wrong place: https://github.com/AlexsLemonade/training-modules/blob/4132971bb861d5e677e851c7c833c123b3d91673/intro-to-R-tidyverse/03-intro_to_tidyverse.Rmd#L465

Somehow the header for Part B the filtering and normalization section of the first scRNA notebook says it is doing dimension reduction, which is not the goal there:

Note that links to this section in the header will also need to be updated

Consider adding @jashapiro's very good pun into dimension reduction slides:

Who's Map is it Anyway?
"Where the axes are made up and the values don't matter."

[allyhawkins]

We should think about adding a PCA plot colored by total UMI count in the normalization notebook because understanding normalization and why we do it can be confusing.

All notebook changes (both in this and the exercise repo) have been dealt with. Only other changes for this issue are the slide changes.

Slide 13 image has been updated and added to slides. It was on a couple other slides as well, and I added it all around -

Consider adding @jashapiro's very good pun into dimension reduction slides:

I added this as a slide note ;) https://docs.google.com/presentation/d/1W1-rZ1xJROSUC7rOYDJhJ1q-Z9gvdIXS4CzPHluMHnk/edit#slide=id.ge1b592c666_0_0

Should we add a pronouns bullet to the "what is your name" slide? (Actual/serious comment)

I added an intro slide deck for June 2024 (mostly not updated for June 2024 though!) and added pronoun questions (FYI @Jen-OMalley - https://docs.google.com/presentation/d/1dJBlWyNfwZwhBOLqauecvBr-HGQ6yQgG--cKmXZrQyw)
