Update help to explain what error code 002557 is and why it happened

[DuncanHornby]

I ran the delete field tool deliberately on a geopackage to see what happens and I got an error message. This did not surprise me as I have read in the help that I cannot drop fields in a geopackage featureclass. Whilst that is something I would like ESRI to resolve what I was surprised is that there is no documentation on error code 002557 as you can see below.

@DanPatterson , interesting you found that bug report, I did search online help for the code and could not find anything specific. Interesting the error message is for a completely different scenario, deleting all fields in a shapefile and I was trying to simply delete a single field from a geopackage. Either way does seem like the help documentation needs to be updated.

Thank you for reporting this @DuncanHornby 

We are going to treat this as a bug (something that needs fixing) instead of an idea (new feature request) I'm closing this Idea because I've opened an issue for it in our internal doc feedback repository.
