Update docs for the Avro datasource <img width="982" alt="Screenshot 2021-02-17 at 21 04 26" src="https://user-images.githubusercontent.com/1580697/108249890-abed7180-7166-11eb-8cb7-0c246d2a34fc.png"> ### Why are the changes needed? The config exists for enough time. We can deprecate it, and recommend users to use `.format("avro")` instead. ### Does this PR introduce _any_ user-facing change? Should not except of the warning with the recommendation to use the `avro` format. ### How was this patch tested? 1. By generating docs via: ``` $ SKIP_API=1 SKIP_SCALADOC=1 SKIP_PYTHONDOC=1 SKIP_RDOC=1 jekyll serve --watch ``` 2. Manually checking the warning: ``` scala> spark.conf.set("spark.sql.legacy.replaceDatabricksSparkAvro.enabled", false) 21/02/17 21:20:18 WARN SQLConf: The SQL config 'spark.sql.legacy.replaceDatabricksSparkAvro.enabled' has been deprecated in Spark v3.2 and may be removed in the future. Use `.format("avro")` in `DataFrameWriter` or `DataFrameReader` instead. ``` Closes #31578 from MaxGekk/deprecate-replaceDatabricksSparkAvro.
