?sdl returns file encoded as UTF-8 with BOM

Is there an existing issue for this?

Describe the bug

I was trying out the new relay compiler and ran into a weird unsupported character issue. After some research I found out it is due to our schema.graphql file having UTF-8 with BOM and not just UTF-8 encoding: facebook/relay#3798 (comment)

Steps to reproduce

Download your GraphQL schema like this: curl localhost:5000/graphql?sdl -o ./src/schema.graphql

Relevant log output

No response

Additional Context?

The issue is this: https://github.com/ChilliCream/hotchocolate/blob/61936613166e64665ab29d873c965a68084eb0df/src/HotChocolate/Language/src/Language.SyntaxTree/Utilities/SyntaxPrinter.cs#L68

It should be new UTF8Encoding(false) instead of Encoding.UTF8.

I can submit a PR, if there are no objections :)

[michaelstaib]

Sure ... do :)

Fixed this in the relay compiler: facebook/relay#3908, but I think it might still be good to also merge my PR here, since this might also cause issues with other tools...
