[tldoc] updated Polish guide

[Staszek Wawrykiewicz]

I've just finally managed to update the Polish translation of
the TL guide (rev 15442).
One note:
in "Release history" section I'd recomend changing:

< \CDref{texmf-doc/doc/english/tds/tds.html\#Extensions}
< {\texttt{texmf-doc/doc/english/tds/tds.html\#Extensions}}.
> \CDref{texmf-dist/doc/generic/tds/tds.html\#Extensions}
> {\texttt{texmf-dist/doc/generic/tds/tds.html\#Extensions}}.

< \CDref{texmf-doc/doc/english/tds/tds.html\#Scripts}
< {\texttt{texmf-doc/doc/english/tds/tds.html\#Scripts}}.
> \CDref{texmf-dist/dist/generic/tds/tds.html\#Scripts}
> {\texttt{texmf-dist/doc/generic/tds/tds.html\#Scripts}}.

Even if that reflects the older TL layout, there are still active
links, so should follow our changes.

All the best,
