[ upstream commit e5c6372 ]

This commits adds as a first step of the `Setup & Test` job for e2e-upgrade
a simple step to dump the current matrix configuration being tested.

The previous commit, modified the title to simply display the matrix entry
name and mode (e.g., `Setup & Test (ipsec-1, minor)`) rather than the
whole configuration. In UI, that would result to be truncated anyway.

It is true that, given the matrix.name (e.g., ipsec-1), a user can open the
specific file and lookup the configuration required, but I think that
having a step where we dump it would speed up and easy debuggability in CI.

The output would be similar to:

```
> Log Matrix Configuration
Current matrix configuration:
{
  "name": "wireguard-1",
  "kernel": "5.10",
  "kube-proxy": "iptables",
  "kpr": "true",
  "devices": "{eth0,eth1}",
  "secondary-network": "true",
  "tunnel": "vxlan",
  "encryption": "wireguard",
  "encryption-node": "false",
  "lb-mode": "snat",
  "endpoint-routes": "true",
  "egress-gateway": "true",
  "ingress-controller": "true",
  "mode": "minor"
}
```

[ upstream commit 315441c ]

As a follow-up of changes introduced in #44126
to improve the readability of workflow job names in the GitHub UI, this
commit adds the `kernel` parameter to the name too. In OpenSearch,
it would be good to differentiate these jobs by the used kernel.
Given the kernel is a parameter that may vary frequently, it is good to be
able to differentiate runs that used the same configuration but different
kernels. That's also good in case of regressions when changing kernel.

The result will be `Setup & Test (ipsec-1, minor, 5.10)`.
