Dependency of compromised polyfill.io

[shtumi]

According to investigation of sansec.io
https://sansec.io/research/polyfill-supply-chain-attack
the library polyfill.io became compromised and lead potential security risks of malware injection
BazingaJsTranslationBundle contains link to polyfill.io in js/index.html
I guess need remove this legacy dependency by security reasons.

@stof @monteiro What about an official release/tag for the fix? as it currently is only available using dev-master. Sure it is only relevant if the template is used directly but still.

[monteiro]

@AndreasA absolutely. I will do during today.
