Update language versions (#29)

* Update language versions

Language versions are up to date on 7 May 2021. Look at diff to see
more.

Note: I haven't changed LanguageExtn.

* Sort languages by their ids

If a Python script is used, it's better to keep languages sorted
somehow. If so, future diffs will be cleaner. I've chosen sorting by
ids.

Also Ruby 2.0.0p645 (id 8) is removed. I see it's removed from
codeforces as well.
