did:elem example did not working

@OR13 When we resolve the example did `did:elem:EiAS3mqC4OLMKOwcz3ItIL7XfWduPT7q3Fa4vHgiCfSG2A` then following error is thrown:
```
[internalError] Driver cannot retrieve result for did:elem:EiAS3mqC4OLMKOwcz3ItIL7XfWduPT7q3Fa4vHgiCfSG2A: 429 Too Many Requests (Error: could not handle the request )
```
The drivers repo is archived and therefore issues can't be created. This is breaching the rules for [driver development](https://github.com/decentralized-identity/universal-resolver/blob/main/docs/driver-development.md#driver-rules) which says that contact information must be provided.
