Add license field to @gluestack-ui/* scoped packages

[noahlozevski]

The license field wasn't being published in the newer @gluestack-ui/* scoped packages on NPM. Example with @gluestack-ui/overlay, where the license field shows as "none".

I assume the license to be applied to these packages would be the same as the code in the rest of the repo, which is currently set to MIT license. I copied this attribute to all the packages manually, and bumped the version so it can be published and consumed by others upstream.

Adding the correct license is a requirement the CI tool I am working out of right now. I hope if the MIT license isn't the correct license for these packages, I can at least get the discussion going around the topic here.
