Missing .env.example in frontend directory

[LucasLagoeiro]

Description:

Hey guys!!
First of all, great work on BotBrain, really enjoying exploring the project!

While following the tutorial to bring up the web interface, I noticed that the README mentions a .env.example file inside the frontend folder. However, this file is currently missing from the repository.

Suggestion:

Add the missing .env.example file to the frontend directory, like this one:

NEXT_PUBLIC_SUPABASE_URL=""
NEXT_PUBLIC_SUPABASE_ANON_KEY =""
NEXT_PUBLIC_ROS_IP=""
NEXT_PUBLIC_ROS_PORT=""

Happy to open a PR if helpful 🙂
