Slow down the dynamic batch size recovery for eth1 deposit tracker

[g11tech]

Motivation
Rather than increasing the batch size back exponentially (2x on each successful fetch), increase it linearly and slowly to give EL more space to recover when choked (could be doing some internal maintenance for e.g)

This PR slows down the dynamic batch size recovery for eth1 deposit tracker by only incrementing batch size linearly while the decrease is still exponential.
