I forget all the details here but instead of `devtools::install()`,
I'm pretty sure you can just use `remotes::install_local()`.

We also have an experimental workflow that uses pak
(https://github.com/r-lib/actions/blob/master/examples/check-pak.yaml);
and pak should know enough about the full dependency graph to install
all dependencies in the correct order without additional work. This
workflow (and pak) itself, is still a bit experimental but we've
started to move the tidyverse workflows to use pak, and haven't had
many problems recently.
