Internationalization : remove English static strings from javascript files

[JayanthyChengan]

Example 1 :
/src/main/webapp/file-versions.xhtml [Line 27 ]
/src/main/webapp/dataset-versions.xhtml [Line 27 ]

preload_message = "(Loading versions...)"

Example 2 :
/src/main/webapp/loginpage.xhtml [Line 162 ]
"Your Browser does not support javascript. Please use"

Example 3:
src/main/webapp/resources/js/dv_rebind_bootstrap_ui.js
show_info_msg('Edit Dataverse', 'Edit your dataverse and click Save Changes. Asterisks indicate required fields.');

Example 4:
/src/main/webapp/resources/js/mydata.js [Line 318-322] -- View Next... Results...

While looking at the pull request for #5299, I did some research on how to solve this javascript issue, and found a Stack Overflow answer which should solve Example 1 and Example 2.

<script>
    var message = '#{bundle[some.key]}';
</script>

For Example 3, I believe I have a workaround for dv_rebind_bootstrap_ui.js which removes that message text, and properly delivers the text via the dataverse pg manage bean -- to be delivered as part of #5299.

That would leave the mydata.js text as the last remaining unsolved example in this issue.

@mheppler Implemented the above mentioned solution for Example 1 and 2. Thanks.

And handled mydata.js(Example 4) by adding hidden field in dataverseuser.xhtml. Could you please review the code . #5351 ? Thanks
