Review Comment:
   This will require a larger amount of code change than this PR though to 
remove all cases of SpecificDatumReader in the codebase. If users want to use 
java 17 then they will need to be on spark 3.5 anyways. If they are on 3.5 the 
recommendation is always to use the latest patch version.
