syft outputs incorrect license LicenseRef-AND

[Makoto Sato]

What happened:
License BSD-2-Clause AND BSD-3-Clause AND Public-Domain becomes
LicenseRef-AND AND BSD-2-Clause AND BSD-3-Clause AND LicenseRef-Public-Domain

What you expected to happen:
It should be: (BSD-2-Clause AND BSD-3-Clause AND LicenseRef-Public-Domain)

Steps to reproduce the issue:
On alpine linux

# apk add libarchive
# export SYFT_FORMAT_SPDX_JSON_PRETTY=true
# syft -o spdx-json@2.2 / > spdx.json

spdx.json

{                                                                                
   "name": "libarchive",                                                           
...
   "licenseDeclared": "LicenseRef-AND AND BSD-2-Clause AND BSD-3-Clause AND LicenseRef-Public-Domain",

Anything else we need to know?:

Environment:

• Output of syft version: 1.4.1
• OS (e.g: cat /etc/os-release or similar): alpine linux 3.19.1
