[v0.37] Lower retry interval in EN requester engine

[jordanschalm]

Backport #6444

We have observed execution nodes (in particular Mainnet EN1) occasionally fail to retrieve collections using this engine, which can cause temporary execution halts. Setting a retry maximum of 10s empirically results in a much faster recovery from these faults (default is 2m).
