fix: add retries to network tests (#2055)

## Description
Network tests, specifically the [Remote Cidr
Restriction](https://github.com/defenseunicorns/uds-core/blob/988955bba84e5fa997b316e105d7a661e081992b/test/vitest/network.spec.ts#L393-L411)
and other tests that utilize a [curl that verifies response from
google](https://github.com/defenseunicorns/uds-core/blob/988955bba84e5fa997b316e105d7a661e081992b/test/vitest/network.spec.ts#L173-L183)
are very flaky lately.

This PR increases timeout of the curl command to 20 seconds, increases
number of retries to 3, and adds a retry delay of 1 second between
retries.
