Do not auto-case VB tuple names

[hartmair]

Version Used:
16.6.2

Steps to Reproduce:

1. Type the following code in VB.NET
2. Note the different casing between variables (camelCase) and property names (PascalCase), see Deconstructed variables code fix should always camelCase variables #23716

Sub NamedTupleCasing(value1 As Integer)
  Dim a = (Value1:=1, Value2:=2)
End Sub

Expected Behavior:

Nothing happens

Actual Behavior:

The first tuple name is auto-formatted in lower case (the same as the function parameter)

Sub NamedTupleCasing(value1 As Integer)
  Dim a = (value1:=1, Value2:=2)
End Sub
