Pin swift-argument-parser package version to 0.0.2

[n-johnson]

When I was trying to compile locally, I ran into build issues from the swift-argument-parser package - it appears as the API of it has changed. This PR pins the dependency to the exact version specified in the Package.resolved file.

FWIW - I've never written swift before so I don't know if this is the actual correct solution for handling dependency versions. Apologies if this is far off base and a waste of time! Hopefully though if anyone else is trying to compile locally this can point them in the right direction.

Mostly to add for searchability - this was the original error I ran into when running swift package update && swift build -c release
