v0.3 Reverse Proxy Support 🌐

With this release streamlink-webui now has support for reverse proxys and setup behind a domain.
I've also improved the startup by using a shell script to apply different env variables set inside Docker to the application at runtime.

Look here for instructions on how to set streamlink-webui up behind a domain.

This is one of the first public releases which is considered alpha, bugs are expected.
Please report any issues or suggestions via Github Issues.

Special Thanks to @marcopeocchi for helping me with the pinia storage to apply the BASE_URL at runtime. ❤️
