Upkeep - fix doc issues + update CI + drop crayon

[olivroy]

I think that ggstance is no longer needed (due to change in jtools) https://cran.r-project.org/web/packages/jtools/news/news.html, but I noticed that broom.mixed was required to run tests, so I added it instead. This is helpful since ggstance is deprecated and the maintainer says the last release was the last one on CRAN.

Updated github actions with usethis::use_github_action() (you may get a failing coverage action, which is fixable by following guideline in r-lib/actions#834

Removed a linewidth warning from ggplot2 3.5.0, (caught from running tests)

I didn't update the vdiffr snapshots, since I am running the dev version of ggplot2 3.5.1.9000.

I replaced the tests wrapped in if (requireNamespace()) by appropriate skip_if_not_installed() instead.

Happy to answer questions.

Cheers

Thank you @olivroy! I made a couple changes to the actions since I deploy to Netlify rather than Github Pages, but otherwise this is great and super helpful! There's a check failure in these tests due to something I did in the main branch before merging but this looks good to go.

Apologies for not noticing that! Thanks for your diligence
