Admin Dashboard: Remove step on color palettes

[MaoShizhong]

Because

As per the comments below, removed the color palettes step entirely as not vital for the project.

The current link text for the Tailwind colour palettes page just says "Tailwind", which can be made more descriptive since it links to a specific page within that site. Over the months there have also been a few questions implying people think they need to use Tailwind for this, and I suspect omitting "Tailwind" from the link text may get the point across that it's just some colour palette suggestions?

On second thought, do we think we actually need to link to anything in this step or perhaps even include this step at all? I wonder if we can just omit this step entirely and if people want to search up colour palettes then that's just a google search away, and it might pull focus away from wasting time on design elements/colour theory etc. (which has been an occasional question in the community, not necessarily due to this project though)?

Those sound like solid reasons for removing to me @MaoShizhong!
