bor: increase max limit for list span api

[shohamc1]

Description

The max limit of spans/list api is set to 20 which is very small. Currently each span is around 6 KB, we can fit ~160 in a 1 MB response size. This PR sets the limit to 150 to account for future span size growth.

Context: Erigon would like to efficiently fetch spans from heimdall for an improved initial sync mechanism. We would like to batch fetch spans cut down the number of requests sent to the heimdall service.
