Polyfill the window.customElements (#23592)
Related: #23590

Reference:
https://github.com/webcomponents/polyfills/tree/master/packages/webcomponentsjs

It seems that there are some users using old browsers, so the
`window.customElements` need polyfill.

The Custom Elements would help a lot for Gitea's UI problems, including:

* `<span class="js-pretty-number">`
* `<time data-format>`

So it's worth get polyfill.
