Upgrade @tailwindlabs/headlessui lib when available

[vnugent]

Background:

In LeanPopover.tsx the onClick should have been on Popover.Button. But due to a bug, the button ignores user-defined onClick prop.

        <div onClick={onApply}> 
          <Popover.Button className='text-primary-contrast bg-slate-800 rounded-md px-2 py-0.5'>
            {btnApplyLabel}
          </Popover.Button>
        </div>

To do:

• Check to see whether Properly merge incoming props tailwindlabs/headlessui#1265 has been released
• upgrade@tailwindlabs/headlessui lib to newer version
• Remove outer div and add onClick to the button, ie, <Popover.Button onClick={onApply} ...

Hey @vnugent, didn't see a way to assign this issue to myself, but created a pull request to address it: #300

This is my first PR for open-tacos, so let me know if I missed any steps in the process.

I think only project's team members with Write permission can assign issues. I'm going to send you an invite. Thanks for the PR!
