feat(902): select panel with min and max size

[mutebg]

closes #902

What

1. Background - we need different size on the panel
2. What did you do - added min and max width to the select panel, that way consumers can have more control of its size
3. What does the reviewers should expect

I have done:

• [ ] Written unit tests against changes
• [ ] Written functional tests against the component and/or NewsKit site
• [ ] Updated relevant documentation

I have tested manually:

• [ ] The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• [ ] The screen reader reads and flows through the elements as expected.
• [ ] There are no new errors in the browser console coming from this PR.
• [ ] When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• [ ] The Playground feature is working as expected
