`ruff server` and `pyright` at the same time.

Description

I cannot have both ruff server and pyright running at the same time, it is annoying.

Reproduce

jupyter_server_config.py:

c = get_config()  # noqa

c.ServerApp.open_browser = False
c.LanguageServerManager.autodetect = False
c.LanguageServerManager.language_servers = {
    "pyright": {
        "argv": ["pyright-langserver", "--stdio"],
        "languages": ["python"],
        "version": 2,
        "mime_types": ["text/python", "text/ipython"],
        "display_name": "pyright",
    },
    "ruff": {
        "argv": ["ruff", "server", "--preview"],
        "languages": ["python"],
        "version": 2,
        "mime_types": ["text/python", "text/ipython"],
        "display_name": "ruff",
    },
}

settings:

"language_servers": {
   "pyright": {
        "priority": 500,
        "serverSettings": {}
     },
     "ruff": {
         "priority": 500,
         "serverSettings": {}
     }
},

Expected behavior

To have suggestions from both pyright and ruff.
