Launcher is converting \ to \\\\ in arguments

[peakschris]

The binary launcher in rules_dotnet appears to be converting single backslashes in arguments to 4xbackslashes.

> bazel run //src/mybinary -- --output=D:\temp
INFO: Build completed successfully, 3 total actions
INFO: Running command line: bazel-bin/src/mybinary/mybinary/net8.0/mybinary.dll.bat '--output=D:\temp'
Arg: --output=D:\\\\temp

The program code is:

    static async Task Main(string[] args)
    {
        foreach (var arg in args)
        {
            Console.WriteLine("Arg: " + arg);
        }

I believe the issue is coming from this line:

rules_dotnet/dotnet/private/launcher.bat.tpl

Line 62 in ccf87e8

set args=!args:\=\\\\!
