Load all locale once in browser environnement

**Describe the bug**

Not a bug, but actually i have to load every local i want to use this way:
``

My problem is that i want to handle any language the user could have set in his browser using navigator.language :
`let mDate = dayjs(date, formats, 'navigator.language').utc(true).format()`
but without adding all that for all languages available in my .html

**Expected behavior**
I wish a could do it as i use to with momentjs:
``
This include all available locale at once.

Also it seems it could be usefull for anyone trying to dynamicaly get the right locale

I would appreciate any guidance or suggestions from the community on how to achieve this more efficiently

**Information**
- Day.js Version 1.11.10
- OS: windows
- Browser Edge

Start by reviewing how Day.js browser scripts load locale files and how navigator.language is expected to select one. Compare the requested behavior with Moment.js's locales.js example. Done means a documented or implemented way to make all available locales usable without adding one script tag per locale, with the expected browser behavior covered.
