Update "rspec-parameterized" gem when a new version comes out

Currently, only simple variables can be used inside where when using rspec-paramterized.

A new commit has been pulled that adds new parameter types ref and lazy to allow reusing variables across examples: https://github.com/tomykaira/rspec-parameterized/pull/62.

When the next release is out for the gem, we should:

• update our Gemfile
• update the related doc (WIP !60789 (closed))
• refactor our specs to take advantage of ref and lazy wherever applicable.
