Trusting the unit test cases. Though I think it will need a cleaner refactoring. The way it is, it's difficult to understand what it does.

Yeah, I wanted to fully rewrite it, but there are untested things that I don't fully understand, so I opted for maintaining the structure. The relevant part for the change is probably this part that digs into all the YAML tree to later find known keywords: https://github.com/apache/camel-k/pull/2476/files#diff-7e7c57f38d81ba22aab4b4a1ef3d536b46c9d2d9432cb215059c52d57e6090efR140-R154
