fix npm registry flake (#9899)

closes #9909 

This PR addresses an intermittent issue in the CI pipeline where the setup of a local NPM registry occasionally fails during integration tests. The issue occurs within a matrix strategy that runs tests across `yarn`, `npm`, and `npx`. The setup involves publishing packages using Verdaccio with a ci `dist-tag`, which is then used to configure `agoric-cli` with `npm`, `npx`, and `yarn` before running the `yarn integration` test command.

## Solution Implemented
Given that this issue happens occasionally, a retry mechanism has been added to the script. Retry mechanism has been added using the `nick-fields/retry@v3` GitHub Action. This solution configures the setup to retry up to three times, with a timeout of 10 minutes.
