chore(ci): support ecosystem-ci use different npm in different repo

[stormslowly]

Summary

Adjust workflow to support ecosytem CI testing with different version of pnpm.

1. Use verdaccio to setup a mock registery foring publish the current rspack's npm packages.
2. Run ecosystem-ci under the mock registery, as all the current rspack's packages are published. So no matter what the underhood package manager is, it will work all fine.
