Review Accessibility compliance

On top of the things in https://github.com/specify/specify7/projects/12

• Make sure all dialogs with fields have <form> and submit button - this way users can use Enter key to submit the form (which can also be made to close the dialog)
• Try out using screen reader. Apple's VoiceOver might be a good example
• Evaluate usages of role and aria-label. Remove extra usages
• Consider HTML tags: noscript, address, article, aside, section
• Use <output> HTML tax for search dialog results, query results, and other things (it adds aria-live, so test screen reader when queryResultsTable fetched more records)
• Evaluate usages of aria-live and aria-atomic (and add missing)
• Review all aria roles: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques
• Learn lessons from https://react-spectrum.adobe.com/blog/building-a-combobox.html
