core/rawdb: fix bad blocks sorted failure message to map index→number correctly (ethereum#32627)

Fix the t.Fatalf format arguments in TestBadBlockStorage to match the
intended #index output. Previously, the left number used i+1 and the
right index used the block number, producing misleading diagnostics.
Correct mapping improves test failure clarity and debuggability.
