Remove duplicate command line logging in dotnet-ef Project.FromFile

[Copilot]

Addresses review feedback from #37643 to eliminate duplicate verbose logging when executing dotnet commands.

Changes

• Removed manual Reporter.WriteVerbose call in Project.FromFile that logged the command before execution
• Exe.Run already logs commands via its processCommandLine parameter (defaults to Reporter.WriteVerbose)
• The manual logging was also using string concatenation without proper quoting, which could be misleading for paths/args containing spaces

// Before: duplicate logging with improper quoting
Reporter.WriteVerbose(Resources.RunningCommand("dotnet " + string.Join(" ", args)));
var exitCode = Exe.Run("dotnet", args, handleOutput: line => output.AppendLine(line));

// After: Exe.Run handles logging with proper quoting via Exe.ToArguments
var exitCode = Exe.Run("dotnet", args, handleOutput: line => output.AppendLine(line));
