Remove Stuff

[ardguezsoc]

• We should remove the internationalisation of the package, probably we should just keep the english version and using the countryAndRegions property for all the other scenarios. This would make the package a little bit lighter.
• Remove react-select using a normal select
• Remove React Date Picker we should probably try to use lighter options like: https://bundlephobia.com/package/[email protected] vs the current one https://bundlephobia.com/package/[email protected]
