Cheatsheet links are broken

Hi Nathaniel!

I have just started learning R from your online Pirates Guide to R and discovered that some of the links in the Cheatsheets (chapter 1.5.1) are invalid.

I don’t know if you still maintain/update the links but I found their new path on github.

For example the Base R pdf moved from

http://github.com/rstudio/cheatsheets/raw/master/base-r.pdf

and I found it at:

https://github.com/rstudio/cheatsheets/blob/main/base-r.pdf

It seems /raw/master/ has been changed to /blob/main/ for the pdf-fil locations on github.
