Fix gcn_email_notok since our time does not include seconds and EralyWarning notice
The conversion is based on the fact that We now add Z to ISOtime, and we do not add seconds. This merge request can be tested only in playground, where we listen back to GCN notice text.
Example:
- TRIGGER_DATE: 20123 TJD; 179 DOY; 2023/06/28 (yyyy/mm/dd)
- TRIGGER_TIME: 83520.000000 SOD {23:12:00.000000} UT
- 2023-06-28T23:12:00Z
We have that GCN e-mail notice type for EarlyWarning is Early_Warning, while the ivo://gwnet/LVC#S231030av-1-EarlyWarning does not have the underscore.
This merge request fixes that we have the precision to seconds in ISOtime and the added underscore in notice type.
