Update struct comments and remove unused import

Updated the comments for `BumpOptions` struct in `version.rs` to provide more detailed information about each field. Removed an unused import statement in `package.rs`. Also, an optional `dry` field has been added to the `DependentPackage` struct to check simulate run without making any actual changes.
