JetBrains IDEs Plugin

### Clear and concise description of the problem

Currently, there are plugins available for VSCode and Visual Studio, but it'd be great if there was an official plugin for the JetBrains suite of IDEs

JetBrains IDEs support Microsoft's LSP, so hopefully an official plugin would require minimal work on Microsoft's part
