[Feature Request] Update to vue-select 3.x — Add the option to paste several tags at once

[tchapi]

Hi

In the tags field, you cannot at the moment paste a list of comma-separated (or anything-separated) tags. The whole string is parsed as a single tag.

It may be opinionated but I think that tags do not usually contain spaces (or commas, FWIW), and thus the behaviour is rather unusual. When creating, say, an article and inputting tags from another source ('marketing' gave you a list of keywords/tags to put in this article), you want to be able to copy and paste it like you did for the content, the title, or any other field.

If Twill updates its dependency to vue-select > 3.3, it should be possible to add this behavior quite easily by adding a handler to "separate" tags if the value submitted contains a comma (or ; , or a space, or anything — that could be a parameter of the field tag)

This would also allow to tag by entering a comma or a space, which is generally the default behaviour on this kind of field in forms.

See sagalbot/vue-select#971 for reference on the handlers method.
The changelog between 2.x and 3.x seems quite reasonable : https://vue-select.org/guide/upgrading.html#events-instead-of-callbacks

Would that be something interesting ? Happy to help if needed
Thanks !
