Update tabline color

[dakennguyen]

I use vim's tab, and cannot distinguish between active tab and inactive tab. I made a change, so it'll look like this

Feel free to change to any color you like (actually I want the background to be different too, but not sure which color to pick 😂 )

I see, sorry about this! How do you feel about something like this, so that the background of the selected tab is darker. It's similar to what I have for barbar:

    Tabline = { fg = onenord.light_gray, bg = onenord.active },

@rmehri01 yeah I think it looks great!

Sounds good, thanks again!
