Bug 41474: update README to explain that moat-settings project requires jq to be installed

Zstandard (zstd) is used to compress some tarballs and needs to be

installed. You'll also need tar >= 1.31, for zstd support.

The jq tool is required to process the json used to generate the country

list used by the browser's censorship circumvention system.

You also need a few perl modules installed:

- YAML::XS

- File::Basename

                  libparallel-forkmanager-perl libpath-tiny-perl \

                  libsort-versions-perl libstring-shellquote-perl \

                  libtemplate-perl libxml-libxml-perl libxml-writer-perl \

                  libyaml-libyaml-perl git uidmap zstd

                  libyaml-libyaml-perl git uidmap zstd jq

If you are running Fedora, CentOS or RHEL, you can install them with:

              "perl(File::Copy::Recursive)" "perl(String::ShellQuote)" \

              "perl(Sort::Versions)" "perl(Digest::SHA)" "perl(Data::UUID)" \

              "perl(Data::Dump)" "perl(DateTime)" "perl(XML::Writer)" \

              "perl(Parallel::ForkManager)" perl-ph git zstd

              "perl(Parallel::ForkManager)" perl-ph git zstd jq

If you are running an Arch based system, you should be able to install them with:

            perl-sort-versions perl-data-uuid perl-data-dump perl-json \

            perl-digest-sha1 perl-io-all perl-file-slurp perl-sys-syscall \

            perl-parallel-forkmanager perl-xml-libxml perl-lwp-protocol-https \

            zstd

            zstd jq

On Arch based systems you also need to generate some .ph files RBM expects:
