Fixing missing sessions is some pt-BR files and also
one small typo of an hmtl end paragraph </p> in the 21-httprequest.html
of en-US original language file.
Portuguese Brazilian, pt-BR, translation based on v.3.0.1 branch.
The initial efforts started with PR #3100(V.2.0.3) but there were some
problems and the quality needed to be improved. Now I fixed some
failures and reviewed files line by line, double-checked with text editor
and dictionary updated to last ortographic agreement of the portuguese
language; anyway errors still can happen, this is not a robotic translation
and portuguese has a latin branch, so one word in english(sometimes) has
many possible translations in portuguese; just to complicate a litlle
bit.
So we are finally making pt-BR available in Node-Red and hope to just
improve from now on.
Resolves: #3100
