Some .gzip files identified as plaintext AND binary

[SebastianSchildt]

We observed a weird behavior on some gzip files.

Good example:

https://github.com/eclipse/kuksa.val/raw/0.4.2/kuksa_databroker/createbom/licensestore/Apache-2.0.txt.gz

Bad example

https://raw.githubusercontent.com/eclipse/kuksa.val/0.4.2/kuksa_databroker/createbom/licensestore/ring.LICENSE.txt.gz

Used identify version

pip install identify

The "good" file works as expected

$ identify-cli Apache-2.0.txt.gz                                                                               
["binary", "file", "gzip", "non-executable"]

the "bad" one yields unexpected results

$ identify-cli ring.LICENSE.txt.gz
["binary", "file", "gzip", "non-executable", "plain-text", "text"]

For reference, file says

$ file *.gz 
Apache-2.0.txt.gz:   gzip compressed data, was "Apache2.txt", last modified: Tue Nov  8 17:08:57 2022, from Unix, original size modulo 2^32 11356
ring.LICENSE.txt.gz: gzip compressed data, was "ring.LICENSE.txt", last modified: Tue Feb 14 08:21:40 2023, from Unix, original size modulo 2^32 10125

is this a bug?
