Fix documentation compliance issues being overly stringent

[IsakNaslundBh]

Description:

https://github.com/BHoM/BHoM_Engine/pull/3438/checks?check_run_id=34182023890

Checks raised as errors here should not be errors.

1. Descriptions should not be forced as errors on methods in the unit-test folder
2. "input order should match input attribute order" should be a warning, not error.

Steps to reproduce:

https://github.com/BHoM/BHoM_Engine/pull/3438/checks?check_run_id=34182023890

Expected behaviour:

For both of the above errors to be downgraded to warning
