[Refactor:Developer] Replace submitty_count (#56)

### What is the current behavior?
Fixes Submitty
[Issue#11784](https://github.com/Submitty/Submitty/issues/11784) - This
one of the companion PRs to Submitty
[PR#12609](https://github.com/Submitty/Submitty/pull/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.
