Replacing nodes in subnet yinp6

[timk11]

Review from subnet thread:

@timk11

Voted to adopt proposal 134260.

This proposal replaces 2 nodes, both of which appear in the dashboard as “Status: Active”, for the purpose of improving network topology. As shown in the proposal and verified using the DRE tool, decentralisation parameters are improved with respect to country and brought to within the requirements of the target topology.
