Support two parameters in dropdownOffset(mainAxis, crossAxis)

[manojhl]

Hi @danharrin,

I’d like to propose a small enhancement to the dropdownOffset() method on the HasDropdown trait.

Current behavior:
It only accepts a single integer or closure for the offset.

Proposed change:
Allow passing two parameters — mainAxis and crossAxis — like this:

->dropdownOffset(8, -10)

This would enable better control over dropdown positioning using Floating UI’s [offset middleware](https://floating-ui.com/docs/offset), which accepts an object with mainAxis and crossAxis properties.

Importantly, this change would not break existing usage since passing a single parameter would keep the current behavior intact.

Examples:

// Existing usage (single offset)
->dropdownOffset(10)

// New usage (mainAxis and crossAxis)
->dropdownOffset(8, -10)

Would this be a suitable addition to Filament? If so, I can prepare a PR.

Thanks!

Hi, yes I would accept a PR to v4, but please also write documentation for it.
