We are renaming Data Prepper to OpenSearch Data Prepper. We should update the documentation to use OpenSearch Data Prepper where appropriate.

Regarding this, I'm not sure what the correct style approach would be for using both terms - OpenSearch Data Prepper and Data Prepper. I can see why it may be advantageous to use the shorter Data Prepper. So maybe titles and headers should use OpenSearch Data Prepper and the paragraphs can use Data Prepper for shorthand. But, I'd like to get some style guidance on this.

See the GitHub issue in the Data Prepper repository that renamed it. opensearch-project/data-prepper#5128

Version: List the OpenSearch version to which this issue applies, e.g. 2.14, 2.12--2.14, or all.
