Update CI + fix roxygen2 warnings + fix anchored links

[olivroy]

• Update github actions to use standard ones
• Update roxygen2 and address deprecation warnings
• Add anchor links
• Use pkgdown 5 to add a search bar
• Use roxygen markdown syntax.
• Rebuild data with tools::resaveRdaFiles('data') as a R CMD CHECK warning occured.
• Remove example using the albersusa package since it is archived and depends on maptools and rgdal.

The coverage action will likely fail when you merge to main. See r-lib/actions#834

I have trouble using devtools::load_all(). Do you have a tip to use it or you use a different strategy?

Thanks! This is great! Am I correct that we can get rid of the tic stuff then?

I usually just use the keyboard shortcut to build and reload in RStudio. Never used devtools::load_all()

Indeed. I deleted tic.R and .github/workflows/tic.yaml
