Relax template-haskell upper bound for microlens-th

[mpilgrem]

GHC 9.6.1 ships with template-haskell-2.20.0.0.

Tested by building the library on Windows with Stack and the stack.yaml:

resolver: lts-20.15

packages:
- microlens
- microlens-contra
- microlens-ghc
- microlens-mtl
- microlens-th
- microlens-platform

extra-deps:
# template-haskell-2.20.0.0 is currently only a candidate package on Hackage
- url: https://hackage.haskell.org/package/template-haskell-2.20.0.0/candidate/template-haskell-2.20.0.0.tar.gz
- ghc-boot-th-9.6.1
- bytestring-0.11.4.0
- text-2.0.2
- binary-0.8.9.0

Thank you!

@fosskers, many thanks. Would it be possible to revise the package description for microlens-th-0.4.3.11 on Hackage, accordingly?

Looks like the version bump was not sufficient per #165 (I was also able to verify myself). FWIW I think your test didn't work because you used the resolver lts-20.15, which uses GHC 9.2.7. Your extra-dep for template-haskell 2.20 was likely ignored. I sent #166 to fix it and will create a new release after.
