.SYNOPSIS
    Compare two version metadata parts for equivalence using the same pattern as Compare-SemVer.
    This function principally intended to be called from Compare-SemVer, prefer that over this.

.PARAMETER Version1Part
    [string] A fragment of a version for comparing/evaluating just the fragment of the metadata

.PARAMETER Version2Part
    [string] A fragment of a version for comparing/evaluating just the fragment of the metadata
