binding/haskell: Package name should be opendal

[Xuanwo]

Hi, @silver-ymz, I think we should use opendal as the package name in haskell side. And the version should align with opendal's.

name:               opendal-hs
version:            0.1.0.0
license:            Apache-2.0
synopsis:           OpenDAL Haskell Binding

I think we should use opendal as the package name in haskell side.

I agree with it.
