Update .gitignore with extra rules

[platonoff-dev]

Now .gitignore is too simple. In my mind It would be cool to add ignore rules for .idea, .vscode , .python-version, venv. .gitignore files doesn't need to read always and there is no need to keep it so minimal.

Thanks for the report, but I'd like to decline for the reasons I stated here. tl;dr there are countless user-specific changes that could go into any and every repo that exists, which is an unsustainable paradigm.
