typo in the documentation on github pages

[juliam98]

There is a typo in this line of Osprey documentation on github pages:

osprey/docs_source/05-tutorial_cmd.Rmd

Line 17 in 87b32c4

MRSCont = OspreyLoad(MRScont);

Change to:

MRSCont = OspreyLoad(MRSCont); 

I know it's minor, but I copy the commands from this page one by one and keep getting an error cause I forget there's a typo there. Thanks!
