Expected result: “Unity Forum” is not listed
Actual result: “Unity Forum” is listed

Reproducible with: 2022.3.64f1, 6000.0.56f1, 6000.2.3f1, 6000.3.0b1

Reproducible on: macOS 15.6.1 (M1 Max), Windows 11
Not reproducible on: no other environments tested

Note:
- In 2022.3 and 6000.0, both Unity Discussions and Unity Forum options are listed (even though both of them redirect to Discussions page); however, in 6000.2 and 6000.3, only Forum is listed. The expected behavior is that all versions should only list the Discussions page
