Deprecation plan

[sgraf812]

The library mentions the following plan for deprecation

There is an issue in the Cabal issue tracker about adding cabal doctest command. After that command is implemented, this library will be deprecated.

But

• That issue has already been closed (although there is only cabal v1-doctest)
• This library is useful independently of doctest. It's probably easy to say so in retrospect, but I think it should have been given a different name. I like it as a maintained replacement of https://hackage.haskell.org/package/cabal-toolkit.

I use this to initialise the GHC API so that I can compile Haskell code to Core. I used cabal-toolkit before, but that didn't work well with doctest. Hmm. Maybe I should use hie-bios instead? 🤔
Edit: No, I don't think that would work. There's no way I can make sure that the GHC versions match, which is trivial with cabal-doctest and cabal-toolkit.

Regardless, I think it would be good to update that note.

I removed the reference to cabal doctest in 1.0.9.
