Add indentation for changes that are in sub-packages

[UniquePanda]

Currently changes in sub-packages are shown like that:

terser-webpack-plugin (webpack -> *terser-webpack-plugin*)
        * Was updated.
        * 5.3.6 => 5.3.7
@types/node (webpack -> terser-webpack-plugin -> jest-worker -> *@types/node*)
        * Was updated.
        * 18.14.0 => 18.15.3
@types/json-schema (webpack -> terser-webpack-plugin -> schema-utils -> *@types/json-schema*)
        * Was added.
        * Has 0 direct dependencies (not listed here).

It would be easier/nicer to read, if some indentation would be added.
Maybe like this:

terser-webpack-plugin (webpack -> *terser-webpack-plugin*)
        * Was updated.
        * 5.3.6 => 5.3.7
    @types/node (webpack -> terser-webpack-plugin -> jest-worker -> *@types/node*)
            * Was updated.
            * 18.14.0 => 18.15.3
    @types/json-schema (webpack -> terser-webpack-plugin -> schema-utils -> *@types/json-schema*)
            * Was added.
            * Has 0 direct dependencies (not listed here).

This would add indentation for every level of change, although the updated packages are bested deeper than their indentation.
Another possibility would be to add as many levels of indentation as there are levels of packages. However, this might look strange if not all parent packages have been updated as well.
