cratesfyi legacy binary: increase recursion limit

[syphar]

error, only on the server deploy

error: queries overflow the depth limit!
  |
  = help: consider increasing the recursion limit by adding a `#![recursion_limit = "256"]` attribute to your crate (`cratesfyi`)
  = note: query depth increased by 130 when computing layout of `{async fn body of docs_rs_watcher::index_watcher::process_changes()}`

error: could not compile `cratesfyi` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...

can't reproduce locally.

Perhaps just increase it here for the legacy binary?
