Prepare pre-release 2.5.0

Pre-release 2.5.0

We are excited to announce the pre-release of a new feature that will greatly enhance the experience with HLS! With this release, we have added comprehensive support for .cabal files at the IDE level. This includes advanced features such as file formatting, diagnostics, and auto completions.

One of our talented developers, @VeryMilkyJoe, has worked tirelessly on implementing this feature throughout the summer. We are grateful for this hard work and dedication. Now, we are thrilled to share this exciting update with all of you.

To ensure seamless integration, it is important to note that this functionality requires HLS version 1.8.0.0 or higher. Failure to meet this requirement may result in .cabal files being treated as Haskell files. We are aware that there are currently some unrelated error logs present. However, we kindly request our users to ignore these logs for .cabal files as we continue to work diligently towards resolving them.

Please refer to @VeryMilkyJoe's summary for demonstrations, which can be found here.

Thank you for your continued support!

Awesome, thank you very much!

Actually, we are missing one thing

[fendor]

We need to add

    "haskell.plugin.cabal.completionOn": {
        "default": true,
        "description": "Enables cabal completions",
        "scope": "resource",
        "type": "boolean"
    },

to package.json.

In general, in a release, we ought to run haskell-language-server vscode-extension-schema and copy-paste the output into package.json.

However, it is a bit tricky because sometimes, a GHC version you compiled HLS with doesn't have all the plugins available, the output is then incomplete. We have no readily available solution for this issue yet. Related issue: haskell/haskell-language-server#3660

Is there anything else about formatter we need to update?

[fendor]

I don't think so.

LGTM, thanks for updating the documentation
