I translated search strings to Vietnamese.

As far as my AI translator helper can tell, looks good! :)

@cuongtqtran , I'm not sure if you saw them, but there are a couple strings missing from the vi translation for portal also.

Thank you, Cathy, for the reminder. You are the best. I have just added the missing translation strings for the portal as well.

Thank you! :) Looking forward to seeing all these non-English portals fully translated! :)

And you're far too kind. It's the translators who make all of this possible. :)
