Update bridges.md

[RaffaDNDM]

I created a Python script that automates the setup and execution of scripts for Frida 17.x.x using the Python API.
Specifically, the script streamlines several preliminary steps inside a virtual environment:

• installing Node.js and npm;
• generating the Frida agent;
• installing the frida-java-bridge;
• converting legacy JavaScript-based Frida scripts into TypeScript by adding the required import statements to a temporary copy of the file.

Hence I have also opened a pull request on this repository to help others perform these operations directly from their Python code.
