Fix Web Handlers not executing with Re-ask option

[Amnish04]

In #519, I implemented initial support for Web Handlers, which extend ChatCraft's URL handling capabilities.

However, @tarasglek noticed that when a non-matching prompt is edited to a valid url pattern that is configured in Web Handlers configuration, prompt is still sent to LLM instead of invoking the corresponding Web Handler.

I researched a bit and found that the reason for this to happen was that the Resubmit handler function for the message form was not passing the prompt text to the onPrompt function.

This is why the handler wasn't able to determine any specifics about the prompt. I am now passing the text to that handler so onPrompt in ChatBase knows that it needs to be passed to a Web Handler.

Before:

onResubmitClick={async () => {
  await deleteMessages(message.id, "after");
  onPrompt();
}}

After:

onResubmitClick={async (promptText?: string) => {
  await deleteMessages(message.id, "after");
  onPrompt(promptText);
}}

This fixes #541

@Amnish04 The fix looks great and I can confirm it works:
Production Bug (re-asking with a valid PR URL sends message to LLM):

Observed Fix (re-asking with a valid PR URL prompts web handler):

Before I approve this, can you address my comment?
