Spanish translation

[gomezpena]

I noticed a few errors in the spanish translation and a closed issue where a more complete translation was requested but not fulfilled. Therefore,

%\begin{macro}{APA7spanish.txt}
%    \begin{macrocode}
%<*spanish>
\ProvidesFile{APA7spanish.txt}[2021/08/08 v1.00 apa7 configuration for Spanish]

\renewcommand{\lastauthorseparator}{y}% and
\renewcommand{\acksname}{Nota del autor}% Author Note
\renewcommand{\keywordname}{Palabras clave}% Keywords
\renewcommand{\notesname}{Notas}% Footnotes
\renewcommand{\notelabel}{Nota}% Note
%Note

%</spanish>
%    \end{macrocode}
%\end{macro}

I have generated a new cls file and compiled a pdf with positive results.
