Fix translation of "Source action" to Spanish

[garrivjo]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.63, spanish
• OS Version: MacOS Monterey v12.0.1

Steps to Reproduce:

1. Write a Java class with an instance variable
2. Open the context menu. One of the options will be "Acción de Origen", which is an intended translation for "Source action" to Spanish. However, the Spanish translation for Source is "Código fuente"; therefore, the option should be "Acción de código fuente".
