Official CC-BY-4.0 license text is not being matched correctly by LicenseCompareHelper.matchingStandardLicenseIdsWithinText()

When org.spdx.utility.compare.LicenseCompareHelper.matchingStandardLicenseExceptionIdsWithinText() is run on the following CC-BY-*-4.0 license texts, it fails to find any matches:

• CC-BY-4.0
• CC-BY-SA-4.0
• CC-BY-NC-4.0
• CC-BY-NC-SA-4.0
• CC-BY-ND-4.0
• CC-BY-NC-ND-4.0

Furthermore, org.spdx.utility.compare.LicenseCompareHelper.isStandardLicenseWithinText() is also returning false in each of these cases, however org.spdx.utility.compare.LicenseCompareHelper.isTextStandardLicense() (correctly) doesn't find any differences when run on the same texts (and when provided with the appropriate CC-BY-*-4.0 org.spdx.library.model.v3_0_1.expandedlicensing.ListedLicense object).

Perhaps we should add one or more CC-BY- cases to the compare consistency unit test?

This was reproduced with Spdx-Java-Library v2.0.0 and SPDX license list v3.26.0.

Beginne damit, die Abweichung in LicenseCompareHelper.matchingStandardLicenseIdsWithinText(), isStandardLicenseWithinText() und isTextStandardLicense() mit den aufgeführten CC-BY-*-4.0-Texten und den entsprechenden ListedLicense-Objekten zu reproduzieren. Sieh dir src/test/java/org/spdx/utility/compare/LicenseCompareHelperTest.java in der Nähe der Zeilen 986-994 an und füge eine Abdeckung für den Fall der Vergleichskonsistenz hinzu. Als erledigt gilt die Aufgabe, wenn die CC-BY-Varianten erkannt werden und die Konsistenzprüfungen bestehen.
