@jreps this should be now ready for review. I've also tested it locally by fitting two models and viewing them in the shiny since I was worried this might affect that.

I had to make a few other changes to get the tests to pass. Was dealing with some strange test failures that only happened during code coverage in github actions.

• I moved the codecov calculations to the linux runner - for me that one is always faster.
• In response to FeatureExtraction's deprecation of cohortId in favour of cohortIds I had to change getCohortCovariateData to take in cohortIds since it's called through FeatureExtraction::getDbCovariateData
• Due to roxygen 7.3 I changed @docType package in PatientLevelPrediction.R is deprecated so I changed that to the recommended approach.
