docs: Add try-catch to getting started

[AlexKobachiJP]

Not sure if this was left out on purpose to keep the sample as small as possible but I feel that a getting started document should show code that builds without requiring fixes, even if it is as simple as adding a try statement, because it otherwise makes the documentation look sloppy.

(Apologies for not creating an issue first.)

Thanks for contributing this @AlexKobachiJP

Agreed, making the docs closer to reality is needed. At the very least try ... incase someone does copy and paste the snippet. 👍
