Small fix to hello world - was getting an error without this package installed. https://github.com/medplum/medplum-hello-world/pull/70

THank you for spotting this! Unfortunately that is a read only repo, and the source comes from here https://github.com/medplum/medplum/tree/main/examples/medplum-hello-world We may not merge this PR and put the fix in the monorepo. If you have a moment to do so, it would be much appreciated.
