altair configuration and docs

[srnm]

Naively adding the altair-spring-boot-starter to my pom.xml, and copy/pasting the altair variables from the readme into application.yml, doesn't work as expected.

It appears defaultQuery.graphql and variables.graphql are required in resources/ -- and they can't simply be empty files. Cribbing the contents of these files from #229 doesn't appear to work - the browser console reports a JSON.parse error.

What's the format of these files?
Can sample files be included in the altair-spring-boot-starter project?

(The graphiql starter, with copy/pasting from the readme, works as expected because it is possible to comment out the non-existent resources. However, altair appears to be required for subscription support.)

thanks
