Little word fix in Spanish documentation

[nicktify]

Hello. This is a little fix on Spanish documentation.

The issue:

Proporciona un definición implícita de...

Should be:

Proporciona una definición implícita de...

In this case, using "un" is wrong because the word "definición" is a feminine word and not masculine.

So, "una" is the correct form.

We use "un" for masculine and "una" for feminine.

Hope this little fix was helpful. Thanks for your time.
