updating deprecated command

[crosbymichael1]

When running this script I get the following warning:

Flag --delete-local-data has been deprecated, This option is deprecated and will be deleted. Use --delete-emptydir-data.

Updating the command now before its completely removed

@crhuber Can you please take a look at this one?

@chadlwilson are you able to review this please?

I'm not a hellofresh person, so don't have ability to run workflows or merge.

It's probably OK to do this now, since it seems the new flag was introduced in kubectl 1.20.0, but have to keep in mind it will break the tool when used with older kubectls, and kubectl versions have to be kept a single version away from the kubernetes API server version.

EKS seem to still have Kubernetes 1.18 and 1.19 and technically kubectl 1.20 is not guaranteed to work on 1.18, however 1.18 ended EKS support in March 2022, and 1.19 recently, so I think this is probably OK. Not sure if they have started force-migrating clusters yet.

This command has fully been removed in the latest kubectl so this project no longer works until this is merged.

Based on #138 it's clear this repo is abandoned. Might might to review forks such as https://github.com/deinstapel/eks-rolling-update
