Replace the ancient (2015) Tor V2 hardcoded seeds with new Tor V3 ones. This needs to be done before 0.22 to make sure onion-only testnet nodes can still connect to the network. Continues #21560.
Ways to test:
src/chainparamsseeds.hwithcd contrib/seeds && python3 generate-seeds.py . > ../../src/chainparamsseeds.h, check if git tree stays the same.bitcoind -testnet -onlynet=onion -proxy=127.0.0.1:9050(or delete~/.bitcoin/testnet3/peers.dat), check if it is able to connect to the network and get blocks.Thanks to jonatack for providing the list.
