removed Startup function from ProviderQueryManager

CHANGELOG.md

@@ -67,6 +67,7 @@ The following emojis are used to highlight certain changes:
 - `routing/http/server`: exposes Prometheus metrics on `prometheus.DefaultRegisterer` and a custom one can be provided via `WithPrometheusRegistry` [#722](https://github.com/ipfs/boxo/pull/722)
 - `gateway`: `NewCacheBlockStore` and `NewCarBackend` will use `prometheus.DefaultRegisterer` when a custom one is not specified via `WithPrometheusRegistry` [#722](https://github.com/ipfs/boxo/pull/722)
 - `filestore`: added opt-in `WithMMapReader` option to `FileManager` to enable memory-mapped file reads [#665](https://github.com/ipfs/boxo/pull/665)
+- `bitswap/routing` `ProviderQueryManager` does not require calling `Startup` separate from `New`. [#741](https://github.com/ipfs/boxo/pull/741)
