Subject: [PATCH] Add bounds to `base` in Haskell template
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`cabal check` fails if bounds are missing, so this is needed for
`validate-template` to succeed on Haskell. If these bounds turn out to be
incorrect downstream (for example, after unsupported GHC versions are removed),
it will be discovered by CI anyway.

Unfortunately, this isn’t enough to get `cabal check` passing. It will also need
to have core/src/ created, which requires sellout/flaky#183.
