## What changes were proposed in this pull request? This generates a documentation for Spark SQL built-in functions. One drawback is, this requires a proper build to generate built-in function list. Once it is built, it only takes few seconds by `sql/create-docs.sh`. Please see https://spark-test.github.io/sparksqldoc/ that I hosted to show the output documentation. There are few more works to be done in order to make the documentation pretty, for example, separating `Arguments:` and `Examples:` but I guess this should be done within `ExpressionDescription` and `ExpressionInfo` rather than manually parsing it. I will fix these in a follow up. This requires `pip install mkdocs` to generate HTMLs from markdown files. ## How was this patch tested? Manually tested: ``` cd docs jekyll build ``` , ``` cd docs jekyll serve ``` and ``` cd sql create-docs.sh ``` Author: hyukjinkwon <gurwls223@gmail.com> Closes #18702 from HyukjinKwon/SPARK-21485.
