Remove find polyfill?

[Ilya Ivanov]

Adding polyfills is in the consumer code responsibility according to Vue Cli developers guie (see, https://cli.vuejs.org/guide/browser-compatibility.html#polyfills-when-building-as-library-or-web-components). Also, Vue Cli is able to auto-detect and inject required polyfills based on browserslist file.

So, what do you think on removing this from the repo?

Thanks in advance!
