Components that offer to open an editor should specify the `override` that makes most sense

This is a follow up from https://github.com/microsoft/vscode/issues/124122 (cc @andreamah) and my review from https://github.com/microsoft/vscode/pull/124394. In https://github.com/microsoft/vscode/issues/124122 the issue at hand is that a UI piece in VSCode provides support to open editors (in this case the Outline view). If the user has configured the default editor to be an editor that is different from what the UI piece is intending to open, you get the wrong editor opening based on the user action. I see that https://github.com/microsoft/vscode/pull/124194 tries to resolve this by teaching the outline view which `override` to use via probing on the `viewType` property (which only exists on notebooks and custom editors currently). I think there are 2 issues to follow up: **Outline** The outline view works with outline providers that can return the outline for the given active editor. Currently I see 2: * `notebookOutline` * `documentSymbolsOutline` Both implement a method `reveal` which is called when you click on an entry in the outline (and I think even when you use breadcrumbs too). I think a better fix for https://github.com/microsoft/vscode/issues/124122 would be to: * explicitly pass in the right `viewType` for [`notebookOutline#reveal`](https://github.com/microsoft/vscode/blob/7ea5b137eaf1771e3fa2c7b569b2fca880db12b8/src/vs/workbench/contrib/notebook/browser/contrib/outline/notebookOutline.ts#L541-L541) implementation based on the editor * enforce to use a text editor in [`documentSymbolsOutline#reveal`](https://github.com/microsoft/vscode/blob/3b87c36e2dc5a9a6f61fd11daca1e9316474ebdc/src/vs/workbench/contrib/codeEditor/browser/outline/documentSymbolsOutline.ts#L211-L211) I think fixing the former is straight forward because it looks like the `notebookOutline` is always constructed over a notebook editor where the view type is known. For the latter: we have a service called [`ICodeEditorService`](https://github.com/microsoft/vscode/blob/5c4663baadf575b10b…
