Gordian Server breaks with Bitcoin 23.0

[shannona]

It looks like the main problem is that MacOS binary URL changed from the expected:

https://bitcoincore.org/bin/bitcoin-core-23.0/bitcoin-23.0-osx64.tar.gz

To one of:

https://bitcoincore.org/bin/bitcoin-core-23.0/bitcoin-23.0-arm64-apple-darwin.tar.gz
https://bitcoincore.org/bin/bitcoin-core-23.0/bitcoin-23.0-x86_64-apple-darwin.tar.gz

(There are also DMGs, but I presume the tar.gz is still preferred.)

Download now needs to occur from:

bitcoin-${processedVersion}-`uname -m`-apple.darwin.tar.gz

The uname -m command from the command line can provide the architecture. The uname() command in Swift can do the same, per this [see the currently 4th answer], but it'll tell you arm64 if it's running in Rosetta, which Gordian Server will be, so we presumably want to get the command-line answer to get them Bitcoin proper running efficiently on the appropriate architecture. (Hopefully that won't also be running in Rosetta since it's a script, but we won't know until we test.)

So, my suggestion is:

1. Move the final composition of the download URL from GordianServer-macOS/Helpers/UrlRequest.swift to GordianServer-MacOS/Scripts/Standup.command to take advantage of the uname -m command line option.
2. Adjust the URL for apple-darwin instead of osx.
