Update metadata for LoongArch64 (api is empty, should be python3) #376

Plugin: LoongArch64 by Noah1
Repository: https://github.com/noah0x1/LoongArch64

The extension was originally submitted as a native plugin, so its metadata on extensions.binary.ninja has an empty api. Since release 0.3.0 it is a Python plugin (a Python loader for prebuilt native binaries), and the plugin.json of that release contains "api": ["python3"] and "platforms": ["Linux"].

The extension manager still uses the old metadata. Installing shows “Plugin doesn’t support any of (python3, debugger, target)”, and after a forced install Binary Ninja 6.0.10601 logs:

ValueError: Plugin 'LoongArch64' API name '[]' is not Python

Could you update the extension’s api to python3, and the platforms and short description to match plugin.json? Thanks :-)
