Support latest versions of Bitcoin Core

[thobson88]

Our ION installation docs recommend Bitcoin Core v24.0.1 because Sidetree requires a legacy wallet type which is deprecated in more recent versions.

Already in v24.0.1 we have to pass the descriptors=false parameter to the CLI when creating the wallet:

bitcoin-cli -named createwallet wallet_name="sidetreeDefaultWallet" descriptors=false

In the latest version v28.0 (as of Nov 2024), the above command fails unless bitcoind is started with the deprecatedrpc=create_bdb flag, so the docs will need to be updated here so the command to create the alias for bitcoind becomes:

echo 'alias bitcoind="/usr/local/bin/bitcoind -conf=$BITCOIN_DATA/bitcoin.conf -deprecatedrpc=create_bdb"' >> $SHELL_CONFIG; source $SHELL_CONFIG

With this change, the above createwallet CLI command succeeds (albeit with the warning about legacy wallet type being deprecated, which is already mentioned in our docs).

However, there is this new invalid_magic_bytes error when starting the ION bitcoin microservice:
