Update the Hive documentation for 4.0.0-alpha-1

With the help of Kristine Hahn we created the documentation for the Hive 4.0.0-alpha-1 Iceberg integration. See: hive-ice.pdf

@rdblue, @samredai: What do you think about the following proposed menu structure:

Hive -+-- Getting started
      +-- Type compatibility
      +-- Hive 2/3
      \-- Hive 4.0.0-alpha-1
           +-- DDL
           +-- DML
           \-- Configuration

hive-dev-box is being used to run all the unit tests of hive/master / metastore integration tests and sometime in the future some smoke tests - so in most cases it should work 😃 I don’t say it’s official…but I think its the easiest way to spin-up Hive for some testing ; there are some timestampted labels if you want to be sure to use a specific version…

@samredai: Created the #4915 with the following changes:

• Type Compatibility - no change here, left it at the end of the page
• Added several paragraphs:
  • Feature support
  • DDL Commands
  • DML Commands

Could you please review? Thanks, Peter
