Imports in NPM Packges broken (missing js extension)

[jogibear9988]

Describe the bug
I try to load dayjs directly as esm module via a importmap.
This is not possible, cause the imports in the npm module ar emissing the .js extensions

Expected behavior
all imports in javascript should contain extensions

Information

• Day.js Version : newest

+1 the import as described in the documentation does not work:

import AdvancedFormat from 'dayjs/plugin/advancedFormat' // ES 2015

It should be:

import AdvancedFormat from 'dayjs/plugin/advancedFormat.js' // ES 2015

I opened a PR to fix this.

Thanks for this. I was having a hard time figuring out how to use the plugins with ESM.
