Update name of ten-block-mission for experience-cs

When I ran the rake task locally, I saw the following output:

    > bundle exec rake projects:create_experience_cs_examples
    Scratch project with identifier 'experience-cs-example' already exists
    Scratch project with identifier 'experience-cs-example' has not changed
    Scratch project with identifier 'dialogue-in-scratch' already exists
    Scratch project with identifier 'dialogue-in-scratch' has not changed
    Scratch project with identifier 'ten-block-mission' already exists
    Scratch project with identifier 'ten-block-mission' updated successfully
    Scratch project with identifier 'blank-scratch-starter' already exists
    Scratch project with identifier 'blank-scratch-starter' has not changed
    Scratch project with identifier 'lets-explore-scratch' already exists
    Scratch project with identifier 'lets-explore-scratch' has not changed
    Scratch project with identifier 'transforming-sprites' already exists
    Scratch project with identifier 'transforming-sprites' has not changed

This suggests that only the `ten-block-mission` project was updated as
intended. I then ran the following command to check the attributes for
that project had been updated correctly:

    > rails r "pp Project.only_scratch(true).find_by(identifier: 'ten-block-mission')"
     id: "2b037df1-3140-47ae-8c05-7dc83ea76a94",
     user_id: nil,
     name: "Ten Block Mission",
     identifier: "ten-block-mission",
     project_type: "scratch",
     created_at: Thu, 01 May 2025 15:01:55.815684000 UTC +00:00,
     updated_at: Tue, 13 May 2025 10:33:04.817462000 UTC +00:00,
     remixed_from_id: nil,
     locale: "en",
     remix_origin: nil,
     school_id: nil,
     lesson_id: nil,
     instructions: nil>

I can see that the name has been changed to "Ten Block Mission" as
expected. The only other attribute that had changed was the `updated_at`
as you would expect.
