feat: add node3

[xenowits]

1. Add a new node (node3) and a new teku vc (vc3-teku) so as to bring the charon cluster node count to 4
2. Update ports for validator-api and p2p-tcp

Looks good to me, but still need to change what's happening in bootnode.yml init container.

My feel is we shouldn't have a shared PVC at all for these nodes, and instead we should inject everything in as configmaps + secrets. 1 config map for the definition. 4 secrets for the ENRs for each charon. and 4/8 secrets for each keystore.json and keystore.txt that need to be mounted into the VC

^ This could be something @eth2devops might explain to Abhishek and Dhruv on a call some time 😇 Good learning opportunity for config+secrets+volumes+lifecycle in k8s.

That is great! I will explain the @dB2510 and @xenowits the current solution and how this cycle works, then we can agree on a new way without using a shared volume.
