[Refactor:Developer] Replace submitty_count

[dagemcn]

What is the current behavior?

Fixes Submitty Issue#11784 - This one of the companion PRs to Submitty PR#12609.
The tutorial courses 04 - Python Static Analysis, 06 - Loop Types, and 07 - Loop Depth all use submitty_count in their autograding configs. This command is being deprecated, so we should update it.

What is the new behavior?

submitty_count has been removed from 04 - Python Static Analysis and 06 - Loop Types and replaced with submitty_count_ts in preparation for deprecation. For 07 - Loop Depth, there was no equivalent functionality present in submitty_count_ts so the testcase is entirely commented out.

Other information?

This specific PR is not a breaking change. However, the other PRs accompanying this one are breaking PRs.

Tested that all homework configs still build and their accompanying still submissions work as intended.

I noted some small fixes that need to be made.

I am concerned that anything testing this gradeable will be expecting autograding results. But, it does look like the cypress spec 'verify_tutorial_courses' only checks if you can submit, so it should be fine.

I tested all 3 gradeables affected by this change. 04 python static analysis and 06 loop types look good and behave the same way before and after the changes from this PR. As for 07 loop depth, we will just need to make sure that turning off autograding for it doesn't break any testing or anything.
