* Corrected small typos around resistor bands.
* Due to failing CI, alterations to the test generator script were needed.
The generated vs submitted diff now skips the first three lines of the file
so that the generation date is not picked up and flagged as needing regeneration.
Sadly, a workaround was also needed to prevent Python difflib from noting the difference
anyways and producing an empty "false positive" diff.
All templates and test files also needed to be altered to ensure that the first three
lines of every test file will always be the autogeneration comment and date.
Hopefully, this will now stop the CI failures without creating any subtle additional bugs.
* Touch up to bowling template. Added back the error raising utility.

* Corrected the macro for comments on the test file.
* Added current_date (utcnow()) variable available for template macros.
* Removed unnecessary datetime import from macros file.
* Regenerated all practice exercise test files to add timestamp.
* Changed `datetime.now(tz=timezone.utc)` to `datetime.now(tz=timezone.utc).date()`
* Second regeneration to remove `timestamp` and just keep `date` for test files.

This test checks that different calls to `iter()` on the same
`LinkedList` instance return independent iterators, which
change state independently of each other.
