NPM package publishing issue

Hi,

I noticed that some code that is present in the repository in git commit tagged as 1.11.9 is not present in the npmjs package that as a library user I install in my node_modules.

Take a look for example this commit:
https://github.com/iamkun/dayjs/commit/fefdcd4b6b807786f65139b6dd801e0014d7dc6f

If package is installed locally with `npm i -S dayjs@1.11.9`, the code in `node_modules/dayjs/plugin/utc.js` does not include the changes from the commit.

Compare commit fefdcd4b6b807786f65139b6dd801e0014d7dc6f with the published dayjs@1.11.9 artifact, focusing on node_modules/dayjs/plugin/utc.js. Start by reproducing the issue with npm i -S dayjs@1.11.9; done means the npm package contains the reported changes from the tagged repository commit.
