Gzip identified as JSON somewhat correctly, but also the output is incorrect

[ross-spencer]

Irakasi Gzip is identified as tldraw which might be correct but there's a problem with the output,, see the line below for an erroneous "a; " in the identification string.

gz-error/gz-error.irakasi	[1]	a; charset=UTF-8; doctype="Tldraw v2"; ref=jrid:0082

There are two problems here:

1. Gzip should not identify as JSON unless it is JSONL -- although it's a useful feature, it should be understood and predictable.
2. The data output should be correct.
