Fix minor typos and grammar issues in prompts

I am already working on this @nidhish, reassigning.

Created MR with various updates to prompts to address some typos and grammar.

I feel that the prompts can be further tightened up and clarified but I think that's for another issue.

Ready for review.

Thank you leo pitt, getting merged.
