Grains exercise typo

The instructions and stub say

# | `$10`    | output    | integer | high 32 bits of output           |

But it should be $v1.

Should I make a PR?

Hi, I opened a PR on GitHub: grains: use `$v1` instead of `$10` as output register for the high word by danilopiazza · Pull Request #196 · exercism/mips · GitHub.

Sorry for opening that before posting on the forum.
