No gem for 1.6.16

[rpsene]

The lack of gem for the version 1.6.16 is breaking builds:

gem update --system; gem install asciidoctor-mathematical 1054.8s => => # installed?' => => # from /usr/lib/ruby/vendor_ruby/rubygems/request_set.rb:173:in block (2 levels)
=> => # in install'
=> => # ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
=> => # bad response Forbidden 403 (https://index.rubygems.org/quick/Marshal.4.8/ma
=> => # thematical-1.6.16.gemspec.rz)`

To overcome this problem we had to set mathematical:1.6.14

It was yanked - https://rubygems.org/gems/mathematical/versions/1.6.16

Is there any chance we can get a 1.6.17 release to permanently squash these 403 forbidden errors? I'm still experiencing issues where gem tries to install the nonexistent 1.6.16 version, and I'd prefer not to have to manually specify 1.6.14 every time I install this gem.

the gem failed (like the old one) due to an issue in our actions. Relevant PR yettoapp/actions#11

should be fixed in v1.6.18
