Mutable custom versioning issue from 5.5->5.6

In 5.6, a handful of new entries in `FCustomizableObjectCustomVersion` were added, including `SetDisplayNamePropertyAsPinNameOfTableNodes`. Looking back at the history, `SetDisplayNamePropertyAsPinNameOfTableNodes` was added originally in https://github.com/EpicGames/UnrealEngine/commit/18e3992548c3c84be378ad90a82b646488c85018. Then `FixedNoPinsInRerouteNodes` was added in https://github.com/EpicGames/UnrealEngine/commit/52ad8a3f1a67676925c5b2359dd9690758171177.

In 5.5 `FixedNoPinsInRerouteNodes` was cherry picked into the release, but `SetDisplayNamePropertyAsPinNameOfTableNodes` wasn't. This is important, because 5.5 shipped with `FixedNoPinsInRerouteNodes` set to a value of `76`. When 5.6 came along and included all of the new versions, `SetDisplayNamePropertyAsPinNameOfTableNodes` was merged into its original slot with a value of `76` as well. This meant that all licensees that went from 5.5 -> 5.6 ended up skipping the `SetDisplayNamePropertyAsPinNameOfTableNodes` fixup and now have invalid/corrupt content. The issue is that you can't even open the content to recreate the broken pieces because it trips asserts and ensures.

Steps to Reproduce

1. Serialize with 5.5 a CO graph that uses Table Nodes. You can use for that the CO the MutableSample project inside the "Showcase/COs/Datatables" directory as it already some of those nodes setup.
2. Open them in 5.6. 

Note : The fix has been pushed to 5.7 so in step 2, to validate the fix, you should open the CO in 5.7 and try compiling it (just in case)
