This upgrades the version of Ormolu required by the HGE repository to v0.5.0.1, and reformats all code accordingly. Ormolu v0.5 reformats code that uses infix operators. This is mostly useful, adding newlines and indentation to make it clear which operators are applied first, but in some cases, it's unpleasant. To make this easier on the eyes, I had to do the following: * Add a few fixity declarations (search for `infix`) * Add parentheses to make precedence clear, allowing Ormolu to keep everything on one line * Rename `relevantEq` to `(==~)` in #6651 and set it to `infix 4` * Add a few _.ormolu_ files (thanks to @hallettj for helping me get started), mostly for Autodocodec operators that don't have explicit fixity declarations In general, I think these changes are quite reasonable. They mostly affect indentation. PR-URL: https://github.com/hasura/graphql-engine-mono/pull/6675 GitOrigin-RevId: cd47d87f1d089fb0bc9dcbbe7798dbceedcd7d83
