Add documentation warnings for Rust, Go, and JavaScript

[alexcasalboni]

3 main changes:

1. Add a --release warning in the Rust docs to clarify that always building with --release might not be ideal if you're prototyping/testing locally and you need debug info in your backtraces
2. Add a -no-debug warning in the Go docs to clarify that by default tinygo includes all debug information and that you can optimize your .wasm file by using -no-debug (up to 75% reduction in size)
3. Add a --disable all warning in the JS docs since many users might actually need to use console.log or new Date() in their component for logging/debugging
