[TagsInput] Allow duplicates

[xkadl17]

🚀 Feature request

Current documentation says that if you want to disallow duplicates in TagsInput, you can use validate function prop to implement logic for such case. Unfortunately I found in the Zag repo code that it actually uses uniq internally to remove any duplicates when adding new value. Would it be possible to have either this "default" solution removed or add a prop to allow duplicates? This should also work then for pasting the values. We need it for our company internal DS.

Code issue in packages/machines/tags-input/src/tags-input.machine.ts:
https://github.com/chakra-ui/zag/blob/main/packages/machines/tags-input/src/tags-input.machine.ts#L615

🧱 Problem Statement / Justification

We need an option to allow duplicates to be used.

✅ Proposed solution or API

Either remove the use of uniq or add a prop to allowDuplicates

Thank you for the great work in Zag/Ark/Panda <3

Basically we have a "sentence" builder component where you can use either predefined tokens or custom values. E.g. <Address>, <City>, <Country>. These commas will be repeating. And before you ask, why not join them after with comma - answer is that you can use different separators per each and also change them (with the editable mode). You can also use the tokens more than once.
