[SPARK-52133] Set Helm chart version to 1.0.0-dev

[dongjoon-hyun]

What changes were proposed in this pull request?

This PR aims to change Helm Chart version from 0.2.0-SNAPSHOT to 1.0.0-dev and revise the description as a part of official release of this chart 1.0.0.

Why are the changes needed?

Like Apache Airflow example, Helm Chart version is independently managed from the application versions (which is Apache Spark K8s Operator).

apiVersion: v2
name: airflow
version: 1.17.0-dev
appVersion: 3.0.0
description: The official Helm chart to deploy Apache Airflow, a platform to
  programmatically author, schedule, and monitor workflows

As a part of the following series of Helm Chart improvement, I believe we are ready to set 1.0.0 for Helm Chart itself at next release, Apache Spark K8s Operator v0.2.0.

• [SPARK-52105] Provide Helm Chart repository #191
• [SPARK-52115] Document Helm Chart #194
