feat(tag): new decorator prop

[ariellalgilmore]

Closes #18002

Updates Tag to include new decorator prop

Changelog

New

• new decorator prop, classes, and styles

Changed

• deprecated slug prop
• update rendering slug to render the decorator component but still set the size if it's an AILabel
• updated tests

Testing / Reviewing

Check tag with AILabel storybook ( i think the tooltip still looks a little odd, but maybe something to fix once people start using it and we can have design take a better look)

TODO:

• remove tag with tooltip before merging!
