Add a headerless jarray parser operator

[RoeiDimi]

Description:

We are using otel-collector as an infrastructure and receive many types of data from a client. The client's sent data is always a form of json and in one use case the json is a simple headerless jarray and so we need a way to parse it and match headers to each field (something similar to what csv_parser does but also supports types supported in a json format and nested objects)

Link to tracking Issue:
#30321

Testing:

• unittests
  All the tests found in csv_parser were copied and adjusted adding test scenarios for different type (number, booleans, null) as well as a test for parsing a nested object as a part of the jarray
• End to end tests
  Used generated traffic on a running otel collector thats using the parser and verified the data is as expected in the end table

Documentation:

• generated
