fix error event

nip05 says `NIP-05 assumes the <local-part> part will be restricted to the characters a-z0-9-_., case insensitive`

So a lot of people is starting the names with uppercase. See here:

`https://nostr-check.com/.well-known/nostr.json`

So I think we should change the regex to accept lowercase or uppercase.

Another way to do it would be to do a `.toLowerCase` at the beginning, but then we would need to do this search ignoring the case:

```
if (!res?.names?.[name])
```

So maybe for now this is enough?
