Master fails to bootstrap with ghc-9.0
There are three issues preventing this currently:
- hadrian requires a hashable version not in the current index state. We can simple bump the index state to fix this.
- The QuickCheck bounds are too restrictive. We can fix this by simply bumping them as well.
- alex versions pre-3.2.6 fail to build: https://github.com/simonmar/alex/issues/179 which the current bounds require.
- alex-3.2.6 should work for master based on #19099 (comment 328864) so we can fix this by bumping bounds.
- The build then fails on building Cabal-3.0.2. Again we can bump bounds to allow for Cabal-3.4
- The build then fails on building hadrian itself.

Which seems fixable.
