Misleading docs for Java Primitives

[dan-f]

Describe the bug

I lost some time today debugging an issue where it seemed that the GraphQLBigDecimal scalar was not working. In fact, it turned out that the name of the scalar needed to be BigDecimal, not GraphQLBigDecimal.

The docs over here directly suggest that we should be naming these scalar GraphQLBigDecimal, which caused runtime errors for me.

To Reproduce

I reproduced this on the 19.1 release, but based on the current code, I'm assuming the bug is still present.

Hello! Thanks for taking the time to post this issue, it's highlighted that all the documentation (including the main graphql-java library) need a review and refresh, definitely don't want anyone wasting time because docs are out of date. As part of that work I'll look into your feedback.

Thanks, finding this helped instead digging into the code.

@dondonz

Any chance you can update the docs?

Weird that such little thing still isn't fixed. I also wasted some time before I downloaded sources for autoconfiguration and it uses "BigDecimal" name instead of "GraphQLBigDecimal".

Would be good if this is corrected in the documentation soon. Same applied for Long instead of GraphQLLong.
