Use file breadcrumbs above TabbedPane instead of full name tabs.

[GraxCode]

Take a look at how IntelliJ implements their tab structure. The name of the tab is the file name without path, and at the top there is a file breadcrumb bar which displays the full path. This saves space and gives more overview.

File breadcrumb component: weisJ/darklaf#237

I'm definitely in favor of changing the tabs to be more Intellij-like, I'll see what I can come up with on my end, thank you for the breadcrumb component link, that should help a lot
