Allow opting out of Floating UI on <Select />

Describe the feature in detail (code, mocks, or screenshots encouraged)

Hi, hope you're doing well! ☀️In the createSelect builder we can pass positioning: null to opt out of floating UI but I couldn't find the equivalent in the select bit docs. This is needed so we can handle the presentation and positioning of options ourselves e.g, using CSS grid or a bottom sheet/dialog. Also Thanks! for #285

What type of pull request would this be?

This is something we have on the roadmap!

Closed in bits-ui@next. Use the Select.ContentStatic instead of Select.Content to opt out of Floating UI.
