Is your feature request related to a problem? Please describe.
cFS documentation workflow is failing with some undocumented parameters:

/home/runner/work/cFS/cFS/osal/ut_assert/inc/utstubs.h:201: warning: The following parameters of UT_ConfigureGenericStubReturnValue(UT_EntryKey_t FuncKey, const void *ValuePtr, size_t ValueSize, UT_ValueGenre_t ValueGenre, int32 DeferCount, const char *TypeName) are not documented:
  parameter 'ValuePtr'
  parameter 'ValueSize'
  parameter 'ValueGenre'
  parameter 'DeferCount'
  parameter 'TypeName'

Describe the solution you'd like
Add documentation

Additional context
This unfortunately is not found by OSAL CI workflows, it was found by CFS workflows only after merging to main. Potentially need to tweak workflows so this type of thing gets detected by the OSAL checks and/or a way to point the CFS workflow at the IC branch so it can be identified before merge.
