RFR: 8051591: Test javax/swing/JTabbedPane/8007563/Test8007563.java fails [v2]

[Abhishek Kumar]

> Test was failing on multiple platforms mainly windows and linux and was problemlisted for all platforms. Increased the delay from 200ms to 500 ms to fetch the correct background color using robot. Now test passed for multiple iteration (~50 times) in CI pipeline for all platforms. Wild imports are expanded and test is pulled out of an extra level of folder.
> Test removed from `Problem-list` file as well.
> 
> CI testing link is posted in JBS.
