feat: support template plugin path

[moreal]

Previously, we need to manage several configuration files for each os and architecture. (e.g., linux-amd64, linux-arm64, etc) because pluginPath field is a constant string.

This pull request introduces a new feature for pluginPath field in appsettings.json-like configuration files.

To use this feature, you must specify version field to 2 first.

{
	"actionEvaluator": {
        "version": 2,
        "type": "PluggedActionEvaluator",
        "pluginPath": "https://lib9c-plugin.s3.us-east-2.amazonaws.com/51c8b73fb5df5cb1e3e3db2d5a8b094dbe5e7ae1/linux-arm64.zip"
    }
}

The actionEvaluator with version: 2 and type: PluggedActionEvaluator, uses pluginPath as template.

The decoder of actionEvaluator replaces the following keywords in pluginPath, with corresponding values.

• <os>: Operating Systems. (macOS → osx, Windows → win, Linux → linux, not supported else) (It is determined by .NET RuntimeInformation.IsOSPlatform(...)).
• <arch>: OS Architecture. (x64 → x64, x86 → x86, Arm64 → arm64, Arm → arm, not supported else) (It is determined by .NET RuntimeInformation.OSArchitecture).
• <rid>: Same with <os>-<arch> (e.g., linux-arm64) (https://learn.microsoft.com/en-us/dotnet/core/rid-catalog#known-rids)

    }
}

Or

{

        "version": 2,
        "type": "PluggedActionEvaluator",
        "pluginPath": "https://lib9c-plugin.s3.us-east-2.amazonaws.com/51c8b73fb5df5cb1e3e3db2d5a8b094dbe5e7ae1/<rid>.zip"
    }
