Typo in Spanish translation

[amyspark]

👋

I just found the following while testing:

gmic-qt/translations/es.ts

Line 647 in c82502c

<translation>Se está ejecutando un comando de gmic.&apos;exécution.&lt;br&gt;¿Seguro que quieres cerrar el plugin?</translation>

'exécution. is extra here, it's mojibake as well.
