Add supported date format with offset in Nuget repository MetaAnalyzer

[sahibamittal]

Current Behavior

Nuget Analyzer has list of two supported SimpleDateFormat which are allowed for parsing the dates being received from the repository, based on limited test data.

Now, as seen in logs, below date format is also received from the nugget repo. This date has offset dateTime and needs to be added to the list of supported formats in order to avoid the ParseException.

Date example: 1900-01-01T00:00:00+00:00
Format needed: yyyy-MM-dd'T'HH:mm:ss

Proposed Behavior

Add the below format in Nuget analyser to support parsing of offset date time :
yyyy-MM-dd'T'HH:mm:ss
