How to test

• Most changes are stubbed or optional properties this time
• However, the proposed scmProviderOptions and textEditorDiffinformation are needed for the update of the vscode built-in extensions. This update is available with this PR: Update VS Code to 1.104.0 and improve extension testing with Theia vscode-builtin-extensions#138. So please go ahead and test those PRs together.

Follow-ups

• [vscode] update VS Code built-in extensions #16279
• [vscode] support git blame information with status bar and editor decoration features via git built-in extension #16280

Looking very good to me, thanks for this PR, Nina!
Only a minor comment on the theia.d.ts comments and annotations. Could you please push an additional commit with this requested change?
I could test the extensions 1.104, all seems to behave fine except the typescript one. But I suspect this is either a misconfiguration on my side or an issue on how the extension works currently (tsserver was deleted by a third party app like antivirus...)

Hi @rschnekenbu, thanks for your review and clarifications, much appreciated!
I updated the respective commit and also added the stubbed annotations to the theia.d.ts file (see 58aeb80)

Regarding the TypeScript extension, I'll have another look to see if I perhaps overlooked that issue on my end.

LGTM, thanks!
The report looks good now, and I could test the extensions with the mode:production on, and the typescript extension is working like a charm. When removing the mode:production from the options, the typescript extension fails. But that is unrelated to the 1.104 API updates.
