ci: retry test failing for getting started integration tests

[frazarshad]

closes: #9325

Description

This PR fixes the issue with the integration (link-cli/yarn) job where on a retry of the step (due to the nick-fields/retry github action), the step fails because of a file already exists error.

The error occurs because we create an bin/agoric file in the previous run and on the retry it tries to recreate the file which already exists.

This is done by removing the bin/agoric file before the next retry occurs

Here is a test run for this PR where the job (link-cli/yarn) failed. The CI job repeats without any issues.

Please rebase on master and remove the lines that redundantly delete the dir.

Also wrt the PR title, this is for the retry of all getting-started tests, not just link-cli.
