Transition deployment to Linux-based service

[StuartFerguson]

Updated createrelease.yml to shift from a Windows-based service to a Linux-based service. Key changes include:

• Targeting linux-x64 in the dotnet publish command.
• Replacing Windows service management with systemctl commands.
• Adding a step to install the .NET runtime on the Linux server.
• Creating a systemd service file for application management.
• Implementing commands to stop, disable, and remove existing services before deploying the new version for a clean deployment process.

To address this issue, we need to add an explicit permissions block to the workflow file. The permissions should be set to the least privileges needed for the actions performed in the workflow. For example:

1. Use contents: read for jobs that only require access to repository content.
2. Add specific write permissions (e.g., issues: write, pull-requests: write) only if required by specific actions.
3. Apply the permissions block at the workflow level to cover all jobs, or to individual jobs if different permission levels are needed.

For this workflow, a reasonable starting point is contents: read, as the jobs primarily involve downloading and uploading artifacts and installing software on servers.
