[Bug][Operators] Error when using min operator using DateTime type

[mapedraza]

Bug description

Operator $min doesn't work to update an existing attribute defined with DateTime and using it for the update as well, returning the following error when trying to make an update: {"error":"BadRequest","description":"date has invalid format"}

This enables some uses cases for date updates coming from IoTA

How to reproduce it

For an existing entity having an attribute using type DateTime and named dateAttr, updating it like this:

curl 'https://orion/v2/entities/E1/attrs?type=T1' \
  -X 'PATCH' \
  -H 'content-type: application/json' \
  -H 'fiware-service: service' \
  -H 'fiware-servicepath: /subservice' \
  --data-raw $'{"dateAttr":{"type":"DateTime","value":{"$min":"2024-04-15T10:59:59.000Z"},"metadata":{}}}'

Expected behavior
The oldest (minimum) date should be stored in the CB

Additional information

Mongo DB supports the use of this operator to compare dates:
