[Documentation][IDE] Add a reference to the docs for the intellij-move IDE

[mkurnikov]

There's a project called intellij-move which is Move Language Plugin for Jetbrains IDEs. It supports all of them, including the free PyCharm Community. IDE should suggest installing it when any .move file is opened, or just download it from the Marketplace in Settings -> Plugins section.
We started it in the middle of 2020, and now it's in quite good shape.

Supported features are:

• Parsing of both Move language and MSL
• Name resolution in Move and MSL
• Types and type inference in Move
• Autoformatter
• Support for Move.toml, move-cli commands, local deps, git deps (partially)

It would be great to have some official recognition of the project, maybe add a link in the docs.

I know Diem started their own language server at https://github.com/diem/move/tree/main/language/move-analyzer, based on rust-analyzer libraries, but it has only some initial implementation. At Pontem, we tried this approach too (code at move-language-server) but it was scrapped when we realized that Diem has started move-analyzer. It has a little bit of parser implemented, I can try to finish the parser later and merge it upstream if needed.

That sounds excellent, thanks for the info @mkurnikov!

@vgao1996 @modocache: I don't have the most context on the status of move-analyzer, but wanted to tag you all to see if bringing in the parser from Pontem's vscode plugin could help.
