What is the current behavior (link to any open issues here)?

Currently, if a user adds the --target-timeline flag to the datasource options to be used in a restore, the operator will also add --target-action which will result in the restore failing.

What is the new behavior (if this is a feature change)?

• Breaking change (fix or feature that would cause existing functionality to change)

Now, if --target-timeline is added to the restore options, the operator will not add --target-action and the restore should proceed as expected.
