Anticipate breaking changes from usethis via a cron job on GHA

[lcolladotor]

We want to implement a cron job as suggested at https://github.com/r-lib/usethis/issues/1856#issuecomment-1581141589 for testing biocthis against the development version of usethis, thus facilitating the detection of issues before most users experience them. This will lead to a more streamlined experience when using biocthis.
