* move Mergify, Restyled, Haskell-CI and Pull Request template to `.github`
* regenerate Haskell-CI file with the new path and new Haskell CI version
* move CSpell from VSCode [Code Spell Checker](https://open-vsx.org/extension/streetsidesoftware/code-spell-checker) extension to `.vscode`
This is a complementary top-level cleanup to #2015.
Make sure Swarm builds with the most recent versions of dependencies. The only one that is still lagging is `filepath`, but `servant` doesn't support `filepath-1.5` so Swarm can't either.
The only real update needed was due to some breaking changes in `aeson-2.2`, but the necessary changes were very minor. Also fixed a few places where GHC 9.8 is generating additional warnings.
Also update our CI: `haskell-ci` recently dropped support for `hlint`, in favor of projects defining their own standalone `hlint` workflows.
Update to use the `lsp-2.4` API. Closes#1350.
Initially I hoped that any `lsp-2.x` would work. However, the `SeverDefinition` record changed in `2.2` so I initially set that as a lower bound. But then it turns out that `2.4` changed which module it is importing `Rope` from; since we work with ropes in the `Hover` module it matters since we have to import the matching module. Updating to the new `Rope` type also required some changes as the API provided by the new `Rope.Mixed` module is a bit different than the old module, so we would not even be able to easily put in CPP to conditionally depend on the right rope module depending on the `lsp` version. Finally, this means dropping support for GHC 9.0 since `lsp-2.4` does not support it.
Along the way I also fixed a minor issue related to showing type information returned by the LSP server, so that it uses `prettyTypeLine` to display the type on a single line (in my editor, when the type does not use a single line it gets cut off). For comparison see also #1610.
This refactoring was a big pain because a lot of things (names of types and constructors, locations of exports, etc...) changed from 1.x to 2.x, but there was not much in the way of documenting what had changed. =( I am pretty sure that all functionality has been preserved but I would appreciate independent confirmation.
This is also a prerequisite for updating other dependencies such as the `base` version (I will open a follow-up PR soon) since the old `lsp-1.x` versions do not allow many newer versions of various dependencies.
Support GHC 9.6 / `base-4.18`, `mtl-2.3`, `megaparsec-9.4`, `servant-0.20`, `servant-docs-0.13`, `servant-server-0.20`, `template-haskell-2.20`, `optparse-applicative-0.18`, fix a bunch of new warnings, and update CI to test on GHC 9.6.
