License formatting issue

The license header file plugin creates a header at the top of every file with a jdoc comment (/**). Spotless however reformats these to a shorter line length. Aka, we have two gradle plugins with conflicting behaviour.

There are two possible solutions to this problem.

1. Make the licence header plugin output a normal block comment (/*) spotless doesn't format these.
2. Change the max line length for spotless that it won't format this jdoc comment anymore.

Whatever solution is chosen we also need to ensure that all licence headers follow the chosen strategy
