Make @inngest/test -> inngest a regular dependency (#725)

## Summary
<!-- Succinctly describe your change, providing context, what you've
changed, and why. -->

Fixes broken JSR publishing for `@inngest/test`.

JSR doesn't support peer dependencies, though a non-optional peer
dependency is identical to a regular dependency in any modern package
manager.

Moving `inngest` to be a regular dependency of `@inngest/test` to
resolve the JSR publishing issue.
