Thanks for the document supplement. Some little nits.

[steveburnett]

Thanks for this! A local build of the docs looks good in terms of formatting and general docs concerns. I'll wait to review and approve until after @hantangwangd's comments are addressed. Tag me in a comment or request a review from me when this is ready!

Hi @hantangwangd, @steveburnett, and @tdcmeehan,

I have modified the Iceberg connector type mapping documentation to implement the comments above and make the content more original. Please let me know if additional changes are needed.

Thanks

Still little nits

@tdcmeehan, I ran into issues while squashing commits in my original branch, so I moved the single commit into a recreated branch. As a result, I had to open a new PR: #22093. Sorry for the inconvenience.
