update github actions

[RMHogervorst]

We could change the github actions to check the package to something like dplyr:
https://github.com/tidyverse/dplyr/tree/main/.github/workflows

ideas:

• of course R cmd check like we already do
• linting step in merge requests
• possibly a cool thing like the styler command inside dplyr .github
• spellcheck?

[RMHogervorst]

also add codemetar update https://docs.ropensci.org/codemetar/#keep-codemetajson-up-to-date
and auto spelling check?

[RMHogervorst]

add https://docs.ropensci.org/pkgcheck/ too?
