MultiSelect component tags seem too large

[vdineva]

No matter which size is picked- they all seem the same and a bit loo large

• medium and large props are not mentioned in the [MultiSelect Props](https://magna-react.vercel.app/components/multiselect#multiselect-props) section

• a minor detail: when the dropdown is open - the chervon should change its direction *screenshots are from https://magnetic-react.cisco.com/?path=/story/core-select-multiselect--multi-select-default

I think this will be resolved with the line height updates in #457
