Adjust ledger-tool bigtable upload starting-slot default value (#29384) 

Currently, if starting-slot is unspecified, a value of 0 will be chosen.
In the common case where someone is operating on a much more recent
range, this would result in a ton of wasted operations & time.

Instead, choose a smarter default value for starting-slot based on what
we detect is currently in the blockstore.
