Many places have the following logic:
```go
func (jobs ActionJobList) GetRunIDs() []int64 {
ids := make(container.Set[int64], len(jobs))
for _, j := range jobs {
if j.RunID == 0 {
continue
}
ids.Add(j.RunID)
}
return ids.Values()
}
```
this introduces a `container.FilterMapUnique` function, which reduces
the code above to:
```go
func (jobs ActionJobList) GetRunIDs() []int64 {
return container.FilterMapUnique(jobs, func(j *ActionRunJob) (int64, bool) {
return j.RunID, j.RunID != 0
})
}
```
