[Bug] Submitting via superpromt does not work in non-english localized Bard

[dundalek]

Describe the bug
Submitting via superprompt does work not when Bard renders interface in non-english language based geographic location.

To Reproduce
Type into super prompt, input text appears in Bard pane, but submitting from superprompt does not trigger the query like for other providers.

Expected behavior
Submitting from superprompt should trigger query in Bard without the need to click the send button manually in Bard UI.

Screenshots
Here is the inspected element. It looks like GodMode matches by aria-label which in my case contains Czech and therefore does not match.

Desktop (please complete the following information):

• OS: Linux (but seems platform independent)
• GodMode Version: v1 beta 8

Additional context
Based on the DOM content, perhaps button.send-button selector could be stable enough and language independent for use as a fallback. Would you be interested in a PR? It sounds like a oneliner.
