fix check-version CI script

[zeroXbrock]

Motivation

now that we're not using workspace versioning, packages[0] resolves to contender_bundle_provider, which is not what we want to check for this release process. We want to check contender_cli, which is packages[1] now.

Solution

it's a kludge but I just changed the target to packages[1]. This whole system needs to be replaced.
