(devel/R-remotes) Updated 2.1.0 to 2.2.0, make test does not pass yet

# remotes 2.2.0

##  New functions and features

* New `system_requirements()` function to query the Public RStudio Package Manager for system requirements for a package (and its dependencies)

* Remotes functions can now install dependencies from additional DESCRIPTION fields, e.g. passing `dependencies = "Config/Needs/website"` will install the dependencies listed in the `Config/Needs/website: ` field in the package's DESCRIPTION.
  Prefixing fields with `Config/Needs` allows them to pass `R CMD check` without a NOTE, so it is the recommended format for these extra dependencies.

* `install_*()` family of functions now use the default branch in the repository, not the `master` branch (@MyKo101,#508).

## Minor improvements and fixes

* Internal functions `remote_download()`, `remote_metadata()`, `remote_package_name()` and `remote_sha()` are now exported, so 3rd party packages could provide methods for new remote types (#509, #56)

* Internal functions `add_metadata()`, `github_remote()` are now exported. They are mainly for 3rd party extensions and should not be used by most users (#485).

* `install_version()` now keeps searching subsequent repositories for the requested version, rather than failing if the version it finds in an early repository is unsuitable. (#305, @kenahoo)

* `install_version()` now understands specifications like '>= 1.0' or '>= 1.12.0, < 1.14' to install the first version of the package it can find that satisfies the criteria. (#305, @kenahoo)

* `install_version()` now avoids use of `base::url()`, as prior to R 3.6.2 it had a bug when downloading large files (#463)

* `parse_submodules()` internal regular expression is now PCRE 2 compatible (#502, @jan-glx)

* `update_packages()` argument `force` has been deprecated and no longer has any effect (#521)

* Another fix for the mixed binary and source dependency issue, it should hopefully be fully squashed now (#296)

* The upgrade menu is now interruptible in RStudio (#489).

* Internal GitHub functions now correctly handle cases when characters are not representable in the default locale, but are representable in UTF-8 (#492).

# remotes 2.1.1

## Minor improvements and fixes

* Installing mixed binary and source dependencies when the latest versions of
  some packages do not have binaries yet should now install dependencies in the
    correct order to prevent load failures (#296)

* `github_error()` now also works when a GitHub (Enterprise) server does not
  return information about the rate limit (@dpprdan, #396, #413).

* `install_gitlab` passes the `quiet` argument on to `gitlab_pat` (@michaelchirico, #437)

* `remotes` is now resilient against installed packages that declare
  `RemoteType: standard` but do not include a `RemoteRepos` or `RemotePkgType`
    field. In such a case, the values for `getOption("repos")` and
      `getOption("pkgType")` will be used (respectively).

* `install_gitlab()` now installs from repositories in subgroups and with dots
  in their name. `subdir` is now an explicit argument instead of implicit in
    `repo` (@robertdj, #259, #420).

* `install()` now passes the ellipsis `...` to `install_deps()` (@Neil-Schneider, #411)

* The tests have been updated to work with newer versions of callr and R 4.0
