f5c87886286473177a67a576d8eac0b32e7f5b97 p2p: update manual tor/i2p/cjdns mainnet seeds for 25.x (Jon Atack)

Pull request description:

  Update the hardcoded P2P network seeds for 25.x after updating the manual seeds and the generation script as necessary. Previous update was #25911.

  The manual seeds are selected for reachability, uptime and service bit 1 and/or curated trusted peers. We need more Tor and CJDNS seeds and some of the current Tor and I2P seeds are no longer reachable.

  Can be tested by following the steps in `contrib/seeds/README.md` and verifying the manual seeds by checking their presence and services in getnodeaddresses and/or connecting to them and checking their services with getpeerinfo and behavior with -netinfo.

  Tool output:

  ```
  $ python3 makeseeds.py -a asmap-filled.dat -s seeds_main.txt > nodes_main.txt
