lint: add dedication role test

[robinwhittleton]

This adds a check for the dto role when a dedication semantic is found. It copies the existing format (e.g. m-031).

I also removed a mistakenly listed unused rule I found in the process.

Thanks! I see you added some files to some unrelated tests, what is that?

Can you also add a test for this?

[robinwhittleton]

There were a couple of tests that had dedication files already that started failing based on missing dto roles; I copied in the jane-austen_test-novel content.opf with an added dto role. I assume that’s the expected approach?

I’ve added a m-090 test but it passes every time with no error, and I can’t work out why. I’ll continue to poke at it.

Worked it out: .DS_Store files had infected the test structure, causing the linter to silently fail early 🤦‍♂️

Great, thanks!
