Support `containers` version `0.8`.

[jonathanknowles]

Version 0.8 of the containers package has been released, but hedgehog and hedgehog-example currently have an upper bound of < 0.8:

• haskell-hedgehog/hedgehog/hedgehog.cabal

  Line 65 in 8deec00

  , containers >= 0.4 && < 0.8

• haskell-hedgehog/hedgehog/hedgehog.cabal

  Line 152 in 8deec00

  , containers >= 0.4 && < 0.8

• haskell-hedgehog/hedgehog-example/hedgehog-example.cabal

  Line 62 in 8deec00

  , containers >= 0.4 && < 0.8

I was able to successfully build with:

cabal build all \
    --constraint=containers==0.8 \
    --allow-newer=hedgehog:containers \
    --allow-newer=hedgehog-example:containers \
    --allow-newer=hashable:containers \
    --allow-newer=wl-pprint-annotated:containers

• Support containers version 0.8. minad/wl-pprint-annotated#12

Thanks, @jonathanknowles. I plan to publish a new revision on hackage (that includes also #543). I will keep you posted.
