chore: remove argTypesRegex and explicitly pass actions args in S2 storybook

[reidbarber]

Fixes the Using implicit actions during rendering is deprecated error in Storybook caused by us using argTypesRegex.

This could be reproduced by typing into the Combobox here: https://react-spectrum.adobe.com/s2/index.html?path=/docs/combobox--docs

Now we pass actions in explicitly. This should also allow us to mock/spy them in interaction tests: https://storybook.js.org/docs/essentials/actions#action-args

✅ Pull Request Checklist:

• Included link to corresponding React Spectrum GitHub Issue.
• Added/updated unit tests and storybook for this change (for new code or code which already has tests).

• Looked at the Accessibility Practices for this feature - Aria Practices

📝 Test Instructions:

Verify that the story doesn't crash when typing into the Combobox.
Verify that the actions are still shown in the actions tab.
