fix(sdk-node): add missing dependency to @opentelemetry/context-async-hooks

[pichlermarc]

Which problem is this PR solving?

See #6188 - @opentelemetry/context-async-hooks is used as a dependency but is only in devDependencies. It should still be pulled in by @opentelemetry/sdk-trace-node though.

Fixes #6188
