Improve file types list for Ruby syntax (#7022)

### Improved list of file types that require Ruby syntax highlighting

- `.ru` files: These are Rackup files and are used for configuring Rack
applications.
- `.thor` files: Used for defining Thor tasks. Thor is a toolkit for
building powerful command-line interfaces in Ruby.
- `.cap, .capfile, and Capfile`: These files are used for Capistrano
deployment configuration.
- `.jbuilder` files: Used for creating JSON responses in a Rails
application.
- `.rabl files`: RABL (Ruby API Builder Language) files are used for
defining JSON templates.
- `.rxml` files: RXML files are used for creating XML responses.
- `.builder` files: Builder templates, which are used for generating XML
and other formats.
- `.gemspec` files: These files define metadata for a RubyGem.
- `.rdoc` files: RDoc documentation files.
- `.thor` files: These files are used for defining Thor tasks.
- `.pryrc` files: Configuration files for the Pry REPL (Read-Eval-Print
Loop).
- `.simplecov`: Configuration file for SimpleCov, a code coverage
analysis tool.

- `path_suffixes` Also new lines the array for readability especially
for diffs.

Release Notes:

- Associated `.ru`, `.thor`, `.cap`, `.capfile`, `Capfile`, `.jbuilder`,
`.rabl`, `.rxml`, `.builder`, `.gemspec`, `.rdoc`, `.thor`, `.pryrc`,
and `.simplecov` files with Ruby.
