💡 Description

When first adding the date installed and date updated, we added a method to calculate those using the home directory.

However, both the Kotlin and the Swift sides of the SDK ended up passing null values for it and it isn't used anywhere. This PR removes the homeDirectory from the AppContext

Hey @yashikakhurana. Thanks for the PR ! I left a comment about changing Generated/ files. You will need to make the change in AS first. The changes for NimbusCreate.swift are good though when we have a new AS version removing home_directory from rust 😄

[issammani]

We can't change files under Generated/ since they will be overwritten by the next AS bump. These are directly generated from uniffi. If you want this to be removed you need to remove it upstream here.

I reverted the changes regarding the generate files, thank you for sharing that. And yes AS pr is up here mozilla/application-services#7085 🙏

[issammani]

Same as above 😄

[issammani]

LGTM ! Thanks. Will trigger CI once the AS bump with the change from mozilla/application-services#7085 lands here
