Fix search provider replace URL with URL with deeplink

[taiebot]

I do not know which other apps use this search provider, but this is used by the tables app. This change replace the URL with a deeplink URL (there was a todo)

This has been tested with the tables app, this will allow sharing links between multiple mailboxes.

Makes sense

nitpick: you can inline the url generation

You have to fix the commit. Message should be fix(search): use deep link. it needs the AI trailer and a sign-off.
