Module breaks services on Amazon Linux 2

Affected Puppet, Ruby, OS and module versions/distributions

Puppet: 7.0.0
Ruby: 2.7.1p83
Distribution: Amazon Linux 2 ARM64
Module version: 10.2.0

How to reproduce (e.g Puppet code you use)

Include the module and set the init_style:

class { 'prometheus':
    init_style => 'systemd',
}

What are you seeing

When this module is added to my puppet configuration, it actually appears to break the service provider on other modules. Here's an example of nginx failing to start properly:

What behaviour did you expect instead

Other services to start correctly

Any additional information you'd like to impart

It appears the amazon linux 2 service provider isn't detected correctly, so I have to explicitly set the init_style

If I remove the puppet-prometheus module from my modulepath, everything works correctly. I can't figure out where this is coming from.
