hotfix: telemetry operator metadata mainnet

[avilagaston9]

Fix fetch operator metadata for mainnet

Description

The first block being read in mainnet was too big, so the operator didn't find any operator update avs metadata uri events.

This PR lowers this number to a smaller value.

This pr also parametrizes the make target to make it more usable, the same as fetch old batches, since it had a similar problem.
