Plugins API: Fields filtering doesn't remove all fields.

[SirLouen]

This is a follow-up for ​#60783

Executing a query towards the Plugins Directory API http://api.wordpress.org/plugins/info/1.2/

Headers: User.Agent = "WordPress/6.9-alpha-60093-src; http://localhost:8889/"
Params:

{
	"action": "plugin_information",
	"request[slug]": "secupress",
	"request[fields][contributors]": "0",
	"request[fields][author]": "0",
	"request[fields][support_threads]": "0",
	"request[locale]": "en_US",
	"request[wp_version]": "6.9"
}

Despite explicitly asking to not include, resulting response is including:

1. Author
2. Support Threads

Also according to docs, some of those fields like:

• author
• author_profile
• support_threads
• support_threads_resolved
• upgrade_notice
• requires_plugin

Are not even being handled there, so it's impossible to decide to filter them out even manually.

reformatted report for readability.

Realistically the remove fields functionality is included/supported for historical reasons, but is likely to be removed in a future API revision (or the client-specified list to be deprecated)

But correct, certain fields can't be removed from the output, that includes, but is not limited to, author, and support_threads. There's a whole bunch of others that likely aren't supported.
