##### SUMMARY
<!--- Explain the problem briefly below, add suggestions to wording or structure -->

Following merge of #59716 revamping ios_facts module, the doc states the 'min' subset in examples but it's not defined in 'Documentation' supported options.
And in module_utils/network/ios/facts/facts.py ; the dict FACT_LEGACY_SUBSETS doesn't mention this 'min' subset.

<!--- HINT: Did you know the documentation has an "Edit on GitHub" link on every page ? -->
