[G12] Typo in analysis procedures

[Michael C. Kunkel]

Greetings,

Shankar notified me of a typo in the g12 procedure note.
If you are using my templates, you should not be affected.
However, please verify your implementation of the g12 momentum corrections.

I have updated the note on GitHub and the g12 wiki.

Thanks Shankar.
