Some of these look like they can be removed

Already marked deprecated for >1 year

• jupyter.runMagicCommands
• jupyter.autoPreviewNotebooksInInteractivePane

Should be deprecated

• jupyter.liveShareConnectionTimeout -- we have removed all our code to support Live Share
• jupyter.allowLiveShare -- we have removed all our code to support Live Share
• jupyter.allowImportFromNotebook -- not used anywhere
• jupyter.ignoreVscodeTheme -- can't support this
• jupyter.textOutputLimit -- should be a core VS Code setting
• jupyter.maxOutputSize -- should be a core VS Code setting
• jupyter.colorizeInputBox -- we have discussed input box discoverability in Improve interactive window input editor styling vscode#128766 and Builtin interactive window support vscode#126415 (comment), and we found that using background colors to draw attention to an area visually poses potential accessibility problems and is inconsistent with other treatments in VS Code. We have opted to render the input box as a notebook cell instead, which should solve the visibility issues that prompted the original colorization treatment. Therefore this setting can be deprecated as it will not be an option moving forward
• jupyter.showCellInputCode -- we cannot support this without significant changes in VS Code
• jupyter.allowInput -- controls whether to show an input box in the interactive window. We cannot support this without changes in VS Code
• jupyter.searchForJupyter -- controls whether to search for a Jupyter-capable interpreter if the user-selected one doesn't work. This has not been supported for ~1 year
