sample outputs from ri String

Description of problem: The 'ri' command of the standard Ruby distribution fails, saying it is not possible to find documentation data. 

The standard Ruby distribution has been installed using dnf.

The problem is to be found in the ruby-doc sub package: documentation data is installed in the /usr/share/ri/system root folder, while it should be installed in /usr/share/ri/${RUBY_VERSION}/system root folder.

The ruby-doc SPECFILE should be modified accordingly in order to fix this issue.

Descrizione  : This package contains documentation for ruby.

How reproducible: Always reproducible 

Steps to Reproduce:
1. Install standard Ruby distribution (sudo dnf install rubygems ruby ruby-doc 
2. Ask for documentation (e.g. ri String), verifying that nothing is found (see attachment)
3. Use the 'ri --list-doc-dirs' to verify the documentation search path.
4. Verify that the system entry of the previous command does not exist.
5. As a workaround, it is possible to create a dummy folder in /usr/share/ri, containing a symlink to the ruby-doc content, to replicate this structure:


/usr/share/ri/2.4.0/system -> ../system

In this way ri happily finds all the documentation required (and installed).

Actual results:
ri cannot find any standard documentation installed in the search path, even if available.

Expected results:
ri should find and report installed documentation in the search path as available.

Additional info:
The example output of 'ri String' command is redirected onto the files attached. Failing.log is when ri does not find any doc, success.log is when it is found, just after creating the dummy folder with the symbolic link.
