(devel/R-remotes) Updated 2.3.0 to 2.4.0

# remotes 2.4.0

* Re-license as MIT. (#551)

* skip tests for `download.file(method = "internal")`, on R > 4.1,
  since that method is now defunct on those versions.

* `system_requirements()` now works as intended if only the `os`
  argument is used (@mdneuzerling, #609)

* `remote_package_name.git2r_remote` and
  `remote_package_name.xgit_remote` now get correct package name from
  HTTP(S) git repo's `DESCRIPTION` file, and thus package's
  `DESCRIPTION` file's `Remotes` field could have
  `git::http(s)://<host>/<username>/<repo>[.git][@ref]` items that
  install remote packages using git via HTTP(S) protocal (@niheaven,
  #603).
