- VirtualizedSectionList/SectionList: replace enableVirtualization prop annotation by correct underlying disableVirtualisation of VirtualizedList (#24312)

Summary:
It seems (I used git history to confirm) that FlatList/VirtualizedList have ([since the begining](https://github.com/facebook/react-native/blame/c13f5d48cfe3e7c0f6c6d0b745b50a089d6993ef/Libraries/Lists/VirtualizedList.js#L79)) a `disableVirtualization` prop.
SectionList ([since it's begining](https://github.com/facebook/react-native/blame/abe737fe746406533798f9670e8e243cb18d5634/Libraries/Lists/VirtualizedSectionList.js#L98)) have a `enableVirtualization` prop, but since SectionList is VirtualizedSectionList which use VirtualizedList, this prop probably never did something. This fix just rename the prop properly so it can have an effect on the underlying VirtualizedList when you use a SectionList.

Since props are spread it's kind of working already, but the flow annotation are wrong (so it tells you it won't work/ you can't use it) which sucks.

(NB: I am doing this since I was trying to use a SectionList with react-native-web & server side rendering to get the all list, you can laugh).
