chore(cardano-node): update to 10.6.3

[michalrus]

Context

• Update to cardano-node/releases/tag/10.6.3.

• I changed how the devshell entry updates its index of CHaP – we need an additional cache invalidation, but it only happens once after updating cardano-node.

Result

❯ cabal run testgen-hs -- --help | head -4
Usage: testgen-hs COMMAND [-v|--version]

  testgen-hs 10.6.3.0 - CBOR test case generator and deserializer for
  cross-checking other implementations
