@sameerz @viadea @GaryShen2008 I just finish the document update, could you please help review the pull request?

Interestingly this looks like it has been interactively edited rather than simply cherry-picked from branch-21.08. There's a number of whitespace changes and other tweaks that I would expect to have come from the original 21.08 source rather than edited here. Otherwise the docs on branch-21.08 are missing those changes, and if someone views the docs on that branch directly rather than via gh-pages they will be missing those changes.

For reference, I am performing a simple diff of the docs between branch-21.08 and this PR to see this, e.g.:

$ cd src/spark-rapids
$ git fetch https://github.com/nvliyuan/spark-rapids.git gh-pages-branch-21.08
$ git diff branch-21.08 FETCH_HEAD docs

There should not be very many diffs remaining, mostly around changes for Jekyll.

@jlowe yes, many of the diffs have been interactively edited. Because there are some files such as supported_ops.md which has so many diffs and it would be better to copy the file. And when I paste the code it was reformated by my IDE, so you see some whitespace. Please refer to this pr which most of the files were updated by cherry-picked. I will close this one.
