Data constructor of VersionIntervals not exported

[Daniel Trstenjak]

Hi David,

> Isn't that `fromVersionIntervals . mkVersionIntervals`?

'mkVersionIntervals' is now only present in the module 'Distribution.Types.VersionInterval.Legacy'.

But 'Distribution.Types.VersionInterval.Legacy' and 'Distribution.Types.VersionInterval' also
contain incompatible type definitions of 'VersionInterval' and 'VersionIntervals'.

Greetings,
Daniel
