Add xray context to /refactor, /fix, and /tests

What does this MR do and why?

The Repository X-Ray is a tool that searches for dependency manager configuration/lock files and then extracts a list of libraries from the content.

This MR adds fetches the latest xray report (if available) for a project and includes this xray_data in the prompt_options that are passed to the aigw for slash commands including /refactor, /fix, and /tests. This will allow us to include the xray report into the corresponding prompts. Given this context the refactoring/fixing/test should be more relevant and higher quality code.

How to set up and validate locally

1. Follow the validation steps in this related MR to trigger creating an xray report for a project in gdk. Make a note of the project id where the xray report was generated: !165391 (merged)
2. Inside https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/gitlab/llm/chain/concerns/ai_dependent.rb#L15 after line 14 add a print statement similar to puts("prompt_options = #{prompt_options}"). This will allow us to verify the xray_data is included in the prompt_options that are passed to the aigw
3. Run gdk and in terminal gdk tail rails to view rails related logs
4. Go to the graphql explorer: http://gdk.test:3000/-/graphql-explorer
5. Run a mutation to trigger /refactor, /fix, or /tests and be sure to pass in the correct id for the project where you created an xray report

   mutation {
     aiAction(
       input: {
         chat: {
           content: "/refactor", 
           currentFile: {
             selectedText: "\n@sold_items = %w( onions garlic potatoes ) \ndef print_report\nputs '*** Sales Report for #{Time.new.strftime('%d/%m/%Y')} ***'\n@sold_items.each { |i| puts i }\nputs '*** End of Sales Report ***'\nend",
             fileName: "hello.rb"
           },
           resourceId: "gid://gitlab/Project/25"
         },
       }
     ) {
       clientMutationId
       errors
     }
   }

6. Look in terminal for the prompt_options that were puts'ed and verify the xray libraries are included for each slash command!
7. To ensure the logic verifying the xray libraries are included in the prompt only when the language matches the file being edited, change your mutation file extension to be different from the xray report language and repeat the above steps to ensure libraries aren't included in the prompt_options.
