chore: update plugin for Intellij 2023.3

[niels-s]

We were updating the plugin to be able to run with Intellij 2023.3 versions. We had to include a few system upgrades to facilitate bumping the maximum build version.

1. Upgrade the Gradle version to 8.5 to overcome the error:

Unsupported class file major version 63

2. Upgrade the Gradle Kotlin and IntelliJ plugins to fix the error:

The binary version of its metadata is 1.9.0, and the expected version is 1.7.1.

I've followed the instructions in
https://intellij-support.jetbrains.com/hc/en-us/community/posts/15634389368722-After-updating-to-intellij-2023-3-my-plugin-is-incompatible-and-does-not-build-anymore and https://stackoverflow.com/a/75180866/1132127 to solve the problem.

Ah I missed there was already #70. @zzehring I'll leave it up to you to decide what PR to pick and merge

Thank you for the PR for supporting 2023.3 👍

I have tried to build the plugin manually and installed it. However, I would see errors like this after installing the updated plugin

Just curious if you have met the same issue? 🤔

Sorry for the delay as I've been on holiday. Thanks for the PR! So, I've merged #70 instead of this one (for now) just due to fewer moving pieces (and it still passed build). I'll cherrypick from here if need be.

Gonna close this one out as #70 seems to be stable.
