Need architecture directory appended to .vscodium-server/bin/<commit>/

[sdturne]

In our organization we use a NFS based file system to house our HOME directories, which can be accessed from machines of different architectures. The current directory structure used by open-remote-ssh places the node executable in the ~/.vscodium-server/bin/<commit>/ directory, which prevents the HOME directory of a given user from being utilized by machines of different architectures. For example, my first use of the open-remote-ssh extension from the workstation where I have VSCodium installed was to connect to a x86_64 machine, which then installed the vscodium-server binaries into the aforementioned location in my network-based HOME directory. If I try connecting to a SSH Target of a different architecture (e.g., aarch64 or ppc64le) the server installation script fails, saying Server script already installed in <location>, followed by Error server did not start sucessfully (sic) because the existing binary is not correct for that architecture. The server installation script needs to append an architecture value (derived from uname -m) to the installation directory so that binaries from multiple architectures can be installed simultaneously.
