Fix use_data() + use_standalone() by not allowing decreasing R dependency

[olivroy]

To fix a drawback from #2043

Basically, if I have a dependency on R 4.1 and call use_data(), it will decrease version to 3.5. Same thing if I require rlang 1.1.4 and call usethis::use_standalone("r-lib/rlang", "types-check")

In short if I have DESCRIPTION

Depends: R (>= 4.1)

And I call this:

usethis::use_data(data, overwrite = TRUE)
✔ Setting active project to "usethis".
✔ Decreasing R version to ">= 3.5" in DESCRIPTION.
✔ Saving "data" to "data/data.rda".

But this is incorrect.

The PR fixes it.

However, I fixed it in the helper function only. If an external package relied on use_package(), it would error.

Agreed that if I call interactively

usethis::use_package("R", "depends", "3.5")

it should decrease by default.

Thanks for catching this! I'm going to solve it in a different way, but am glad you brought it to my attention. I have learned the hard way that use_dependency() is very easy to introduce bugs into, so I'll fix this in use_data().
