onDidAccept proposed APIs don't match naming convention

Maybe they should be onDidAcceptText given #49340 (comment)?

For QuickPick it might have to be onDidAcceptItems because it really fires for all the different 'accept' gestures that should behave consistently for each widget. Needs some more thought.

@jrieken I believe we discussed this, did we conclude that onDidAccept was fine? We could use onDidAcceptValue on InputBox and onDidAcceptItems (although often it will be exactly one) on QuickPick. One reason against being specific was that we would let extensions decide what to 'accept', but we later discarded that reasoning because we expect extensions to consistently accept the value in InputBox and the items in QuickPick and use the buttons for alternative actions (like accepting the value in a QuickPick). Opinions?

Yeah, the rule says on[Did|Will]VerbSubject but we have a few places in which we skip the Subject because its obvious from the context, like WebView#onDidDispose (instead of WebView#onDidDisposeWebview). It never hurts to be explicit but if the context/subject is obvious (which is likely to happen more often with "local/private" events) then it is an option to skip the subject-part

Sounds good. I'll keep the existing naming then. That also makes it somewhat consistent across these interfaces.
