Upkeep for blendR (2023)

[n8thangreen]

• usethis::use_readme_rmd()
• usethis::use_github_links()
• usethis::use_pkgdown_github_pages()
• usethis::use_tidy_description()
• usethis::use_package_doc()
  Consider letting usethis manage your @importFrom directives here. usethis::use_import_from() is handy for this.
• Align the names of R/ files and test/ files for workflow happiness. The docs for usethis::use_r() include a helpful script. usethis::rename_files() may be be useful.
• usethis::use_code_of_conduct()
• Add alt-text to pictures, plots, etc; see https://posit.co/blog/knitr-fig-alt/ for examples

Set up or update GitHub Actions.
Updating workflows to the latest version will often fix troublesome actions:

• usethis::use_github_action('check-standard')
• usethis::use_github_action('test-coverage')
