Documentation of "pattern es" mismatch library code

[AlonsoCerpa]

Inside the Documentation of pattern es, particularly in verb conjugation, there is a table of conjugations for spanish verbs, however, in the table, when the alias is "1sgp+", this doesnt work, because the correct alias is "1sg+" (I noted this observing the library file pattern/text/init.py and going to the line 1937, where the table of conjugation shows the correct alias).

In total there are 6 Alias changes needed for the documentation of pattern es: "1sgp+" -> "1sg+" "2sgp+" -> "2sg+" "3sgp+" -> "3sg+" "1ppl+" -> "1pl+" "2ppl+" -> "2pl+" "3ppl+" -> "3pl+"
