Internationalization : Move English strings from xhtml and java to bundle.properties

[JayanthyChengan]

Find and move all the english strings from xhtml files related to user interface to bundle. properties. This will centralize the words and make it easier to translate into other languages going forward.

@JayanthyChengan thanks for creating pull request #4643! I looked it over and move it to QA at https://waffle.io/IQSS/dataverse

Hopefully, by looking at the "diff" it's easy enough to figure out what to test but if you feel like adding a list here, I'm sure it would be appreciated.

I might need to discuss with dev on the best way to test since I do not know the code.
I will look at the diff to see what sense I can make of it.

OK, I think I was able to locate most strings except for Replication for, Selected (dataverse), and View More Results (due to text being different)
