Update NPM_TOKEN secret

[jcbhmr]

@huwaireb i dont have permissions to edit this repository's secrets lol. if you could, please navigate to https://www.npmjs.com/settings/huwaireb/tokens/ and create a new token with these perms

and then add that to the NPM_TOKEN secret of this github repo. that way when you create a new release on github https://github.com/typst-community/typst.js/releases it triggers npm publish

Gave you admin on typst.js, not sure why it wasn't the case if you were the creator in the first place.
