gh-85988: Change documentation for sys.float_info.rounds (GH-99675)
* Change documentation for sys.float_info.roundsChange the documentation for sys.float_info.rounds to removereferences to C99 section 5.2.4.2.2 and instead place theavailable values inline.* Correction to previous documentation changeNewlines were not preserved in generated HTML on previouscommit. I have changes the list to a comma-separated listof values and their meanings.* Clarify source for value of FLT_ROUNDSClarify the source of the FLT_ROUNDS value andchange 'floating-point addition' to 'floating-pointarithmetic' to indicate that the rounding modeapplies to all arithmetic operations.
