This function adds or updates the Dependencies badge to the README.Rmd.
The first number corresponds to the direct dependencies and the second to the
recursive dependencies.
Note: this function can work with packages not published on the CRAN
and is based on the function gtools::getDependencies(). See also the
function get_all_dependencies().
Make sure that 1) a README.Rmd file exists at the project root and 2) it
contains a block starting with the line <!-- badges: start --> and ending
with the line <!-- badges: end -->.
Don't forget to re-render the README.md.
