Merge #20015: doc: Added default signet config for linearize script

8a4dcda414 doc: Added default signet config for linearize script (gr0kchain)

Pull request description:

  Updated the example-linearize.cfg file to include support for the signet chain network config which is used by the ./linearize-data.py

  Problem:
  Without the signet magic, genesis hash and path config, the linearize-data.py script cannot generate a bootstrap.dat file.

  Example:

  ```
  ./linearize-data.py ./linearize.cfg
  Read 4776 hashes
  Genesis block not found in hashlist
  ```

  Solution:

  Added netmagic, genesis and input example parameters to file. Netmagic in terms of signet is derived from the signet-challenge and not static as with other networks. The provided signet magic is based on the default public signet.

  Resolution

  ```
  ./linearize-hashes.py ./linearize.cfg > ./hashlist.txt
  ./linearize-data.py ./linearize.cfg
  $ ./linearize-data.py ./linearize.cfg
  Read 4776 hashes
  Input file /Users/gr0kchain/.bitcoin/signet/blocks/blk00000.dat
  Output file /Users/gr0kchain/Downloads/bootstrap.dat
  1000 blocks scanned, 1000 blocks written (of 4776, 20.9% complete)
  2000 blocks scanned, 2000 blocks written (of 4776, 41.9% complete)
  3011 blocks scanned, 3000 blocks written (of 4776, 62.8% complete)
  4010 blocks scanned, 4000 blocks written (of 4776, 83.8% complete)
  Done (4776 blocks written)
  ```
