Correct License is not being detected

[carolinamarc]

Description

Running scancode for the following github package (https://repo1.maven.org/maven2/com/toedter/jcalendar/1.4/jcalendar-1.4-sources.jar), it doesn't detect correct the license inside. The text explicitly refers to the LGPL, but scancode incorrectly matches it to the GPL.
Source file: JCalendar.java

Detected License: GPL-2.0-or-later (Match: 3%)
Expected License: LGPL-2.0-or-later (GNU Lesser General Public License v2.0 or later)

System configuration

Which version of ScanCode.io are you running? 32.2.
Are you running the app using Docker? Yes

Thanks for the report @carolinamarc

We should have a new rule added + add required phrases at the detected rule to fix the issue here.

@AyanSinhaMahapatra
this is resolved in #4880
The fix uses required phrases on the existing GPL rule to prevent the false positive and adds a dedicated rule to correctly detect this specific JCalendar LGPL variant

could you take a look when you have a moment?
