[Enhancement] Remove duplicate declarations while sorting

[paulhundal]

When running the sort command, ideally if dependencies are duplicated then they should be consolidated to only the unique list.

dependencies {
  api deps.kotlin.coroutines_core
  api project(':common:public:one')
  api project(':common:public:one')
  api project(':common:public:one')
}

should result in

  api project(':common:public:one')
  api deps.kotlin.coroutines_core
