chore(configs): Adjust file based configs (#3171)

## What ❔
* Add fields to mainnet.yaml so that `zkstack` can create mainnet
ecosystem
* Add comment about typo in `max_acceptable_priority_fee_in_gwei`
(caused problems before)
* Add `l1_batch_min_age_before_execute_seconds` to avoid sending Execute
tx too early

## Why ❔
* To make things work
