What happened?

Description

After enabling feature gate logs.jsonParserArray, when I try to use json_array_parser, it still reports unsupported type 'json_array_parser'

Steps to Reproduce

Try to use json_array_parser in a config file. Then launch otelcol-contrib with --feature-gates=logs.jsonParserArray.

Expected Result

It should launch normally.

Actual Result

It reports unsupported type 'json_array_parser' and exits.

Collector version

Additional context

The parser checks feature gates in init(), which seems to run before the command line arguements have been loaded?
