`docs search` with --json option

Problem statement

Not sure if this is an issue, but I found it slightly confusing that there are two --json options that can be set when using docs search

Specifying the top level --json/--human flag is ignored by the docs search commands (but fails if you specify both).

Only the search --json option is respected.

wt --json docs search --json query

Proposed solution

I guess the docs say that the global options only apply on wt api:

https://github.com/wagtail/wagtail-cli/blob/190d1bee2dad91f79336c3efe68ddbab7f14989d/docs/usage.md?plain=1#L15-L27

But it would be possible to pass the json option through to the docs search command?
