Use rversions::r_release() to get current release version

[csoneson]

Another thought: would it make sense to use

currentR <- as.numeric_version(rversions::r_release()$version)

in place of

bioc-actions/setup-bioc/create-version-map.R

Lines 27 to 30 in 532cbd7

	currentR <- readLines("https://rversions.r-pkg.org/r-release/")
	currentR <- grep("version", currentR, value = TRUE, fixed = TRUE)
	currentR <- gsub(".*version.*([0-9]\\.[0-9]+\\.[0-9]+).*", "\\1", x = currentR)
	currentR <- as.numeric_version(currentR)

The latter still seems to return 4.1.2 while the former gives 4.2.0.
