tools: plugin: Fix broken OpenVINO model link in README.md

Updated a broken OpenVINO noise suppression model link in  
`sof/tools/plugin/README.md`. The previous link was inaccessible,  
preventing users from following the setup steps.  

New link:  
https://docs.openvino.ai/2023.3/omz_demos.html#a-name-build-demos-linux-a-build-the-demo-applications-on-linux  

This ensures users are directed to the correct and updated  
documentation.
