Thank you for doing this! It's greatly appreciated when people take the time to update our tutorials :)

Couple overall things:

• Both in our code and in our docs, we limit the length of a line to 80 characters. Please split the lines you added to adhere to this.
• You can squash these changes into your original changes, and remove the merge commits on your branch. If you're not sure how to do this, we can go over how to do it on Slack.

@SunPeike Could you update the PR description? You don't say anything about Paraview 5.11.1 anymore.
