Metadata for the TeX Live Guides

[Takuto ASAKURA]

Hi Karl, Norbert, and All,

I noticed that there are no doc metadata in the tlpdb for
the TeX Live Guides. For example, 

name texlive-en
category TLCore
revision 51878
shortdesc TeX Live manual (English)
[...]
docfiles size=1355
[...]
 texmf-dist/doc/texlive/texlive-en/texlive-en.html
 texmf-dist/doc/texlive/texlive-en/texlive-en.pdf
[...]

How about modifying the lines to:

 texmf-dist/doc/texlive/texlive-en/texlive-en.html details="TeX Live documentation (HTML)" language="en"
 texmf-dist/doc/texlive/texlive-en/texlive-en.pdf details="TeX Live documentation (PDF)" language="en"

and doing similar for other translations?

Best,
Takuto
