Wrapping Vararg directly in UnionAll is deprecated

[tomyun]

When testing a package indirectly loading SIMD.jl as a dependency, with depwarn=error enabled, I get a deprecation error like this. Julia 1.7.0 and 3.4.0.

ERROR: LoadError: Wrapping `Vararg` directly in UnionAll is deprecated (wrap the tuple instead).

Hey, just wanted to bump on this - getting a similar error in Julia 1.9, SIMD v3.4.4:
