I want to add keybinding: `SPC m = u` should run command `ruff.executeFormat` (only for python buffers). How do I do it? I tried different things eg:\n```\n    \"whichkey.bindingOverrides\": [\n        {\n            \"keys\": [\"m.=.u\", \"languageId:python\"],\n            \"name\": \"Format\",\n            \"type\": \"command\",\n            \"command\": \"ruff.executeFormat\",\n        }\n    ],\n```\n\nor\n\n```\n    \"whichkey.bindingOverrides\": [\n        {\n            \"keys\": [\"m\", \"languageId:python\", \"=\", \"u\"],\n            \"name\": \"Ruff Format\",\n            \"type\": \"command\",\n            \"command\": \"ruff.executeFormat\",\n        }\n    ],\n```\nBut nothing works - the  `u` / \"Ruff format\" is not shown in `SPC m =` submenu for python buffers.","author":{"url":"https://github.com/tkossak","@type":"Person","name":"tkossak"},"datePublished":"2025-04-08T10:23:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/79/vspacecode.github.io/issues/79"}
