Update SAC event doc-comments to CAP-67 shapes (#1956)

### What

The `StellarAssetInterface` doc-comments for `mint`, `clawback`, and
`set_authorized` now describe the CAP-67 Stellar Asset Contract event
shapes.

### Why

CAP-0067 removed the `admin` topic from these SAC events. Also the
trailing SEP-11 asset topic has been there for a while.

### Known limitations

N/A

Close #1955
