Describe the issue

"optional" is spelled "optinal"

Suggestion

Fix the spelling. Try doing a mass check to see where all "optinal" pops up and ensure it isn't supposed to be optional as a potential further fix.

I also saw it in the golang hosting extension under the obsolete add but not a newer and more modern method in the same golang extension file so I'm assuming it was some form of automated documentation error. Or someone was consistently misspelling the word across the code base.
