[Req]: Improve sorting tool

### Contact Details

_No response_

### Explain the proposed feature

The [sorting tool](https://github.com/developertools-tech/developertools.tech/pull/35) is in currently in development, but upon completion it would add a lot of utility if we could add a field for the output separator so you could change a newline separated list to comma separated, etc. (This would also require a sort option of "keep order").

### Explain the possible use cases for the feature

_No response_

### Any other details you would like to provide?

Blocked by #35

Start by reviewing pull request #35, which contains the sorting tool currently blocking this issue. Confirm how the tool handles sorting and output, then add a configurable separator and a “keep order” option so newline-separated input can be emitted in other formats.
