Update Timestamp Extraction description with additional examples for "timestamp.format"

[revzzver]

The "timestamp.format" parameter description does not include any examples for ISO 8601 like timestamps with a 'T' separator for time. Would it be possible to include additional examples such as:

If timestamp is 2022-03-29T23:11:52.054, set timestamp.format to "yyyy-MM-dd'\''T'\''HH:mm:ss.SSS"
