12e6622d - [Support] Avoid setting minor/subminor/build in VersionTuple::withMajorReplaced (#139318)

[Support] Avoid setting minor/subminor/build in VersionTuple::withMajorReplaced (#139318) The expectation of this API is that it only changes the major version of a preexisting version tuple. However, it was adding 0's, which caused unintended changes in serialization or printing. Instead, check for the existence of the non-major parts of the tuple.
