The kaniko flag `snapshotMode` is deprecated in favor of `snapshot-mode`. The default value of `snapshot-mode` is `full`. As a result, the `optimize` flag set in Harness CI's `BuildAndPushToDocker` steps doesn't behave as expected because the `full` mode triggers a full filesystem scan which is slow. The `optimize` flag in Harness translates to `snapshot-mode=redo` which means only filesystem deltas are compared which is much faster.
This change fixes the flag name being sent to Kaniko executor. I verified that the executor present in the current version already supports this flag as shown below:
```
hemanthkumarmantri@Hemanth Kumar harness-core % docker run -it --entrypoint /kaniko/executor plugins/kaniko:1.8.10 --help | grep snapshot-mode
--snapshot-mode string Change the file attributes inspected during snapshotting (default "full")
--snapshotMode string This flag is deprecated. Please use '--snapshot-mode'.
```
