Update Build Documentation for IntelliJ 2023.3.0

I trying to do a release for #91, I checked out the repo and install IntelliJ 2023.3.0. I followed the steps at https://jetbrains.org/intellij/sdk/docs/basics/getting_started/setting_up_environment.html and

- Installed the Plugin Devit plugin
- Downloaded a JDK through IntelliJ and added it to the project: openjdk-21
- Added IntelliJ Platform Plugin SDK: Pointed at install directory for IntelliJ 2023.3.0
- Checked out IntelliJ Community source code and added it to the SDK Sourcepath in Platform Settings | SDK

When I try to build the plugin, I get build errors:

```
clion-cppcheck\src\com\github\johnthagen\cppcheck\Configuration.java:3:36
java: package com.intellij.openapi.options does not exist
```

@firewave Do the build instructions need updated? I know that the guts of this plugin haven't been updated in a long time (e.g., #69 would be ideal). Are you still able to build it on a clean install of IntelliJ 2023.3.0?
