This pull request includes two patches.

The first patch hides the "handout" button if no handout is defined. It makes changes to the handout controller, assessment model, and the show.html.erb view file.

The second patch provides a temporary fix for a chromedriver issue. It adds a fix to the rails_helper.rb file to address a specific version issue with chromedriver.

Please review these changes and test them accordingly.

Description

Hide "download handout" button if assessment does not overwrite handout method, and handout is neither a url nor a file.

Motivation and Context

Removes non-applicable menu items to avoid clutter and confusion. (similar logic for the writeup button was applied in #1615)

Closes #1941

How Has This Been Tested?

• Create a new assessment, observe that "download handout" button is absent
• Set handout to be a random string, observe that "download handout" button is still absent
• Set handout to be a url, observe that "download handout" button appears and works
• Set handout to be a file (e.g. <asmt>.yml), observe that "download handout" button appears and works
• Clear value of handout, define handout method in .rb file as follows:

def handout
    {
      "fullpath" => "<full path to a file>",
      "filename" => "<file name>"
    }
end

Reload config file. Observe that "download handout" button appears and works.
