Extension Pack for IntelliJ

### Description

Coming from https://discord.com/channels/1079625926024900739/1429522693190979685/1482723054143672341

We already created a VSCode extension which include `oxc.oxc-vscode` and `vitest.explorer` VSCode extension.

The same extension pack is missing for IntelliJ/JetBrains Editors.

### Suggested solution

Asked ChatGPT if there is a concept like VS Code `extensionPack` for IntelliJ.

#### 1. Create a normal IntelliJ plugin

You can create it using the IntelliJ Platform Gradle Plugin or the plugin template.

Typical structure:
````
my-meta-plugin/
├─ build.gradle.kts
├─ settings.gradle.kts
└─ src/main/resources/META-INF/plugin.xml
````
#### 2. Declare plugin dependencies in plugin.xml

Add the plugins you want to bundle as required dependencies:
````

com.example.my-plugin-pack
My Plugin Pack
Me

org.intellij.plugins.markdown
com.jetbrains.rust

````
When users install your plugin:

IntelliJ checks whether these plugins are installed

If not, it automatically installs them

So your plugin acts like a plugin pack.
