[gnrt] Simplify the type of traversal root in `fn collect_dependencies`.

`gnrt_config.toml` can only specify a single, mandatory root package -
see:
https://source.chromium.org/chromium/chromium/src/+/main:tools/crates/gnrt/lib/config.rs;l=82-83;drc=bafbc32fa9dd1737bd9919d1544d754d51cf38f8

Based on the observation above, this CL simplifies how `fn
collect_dependencies` receives the graph traversal root - instead of
`Option<Vec<String>>` it now takes `&str`.
