Figure.pygmtlogo: Remove the additional black outline for the black-and-white dark-theme logo

[seisman]

Currently, we add an additional black outline to the black-and-white logo in dark theme. But is it really necessary? Dark mode usually implies a dark (black) background, and the white shape outline is already visually distinct from the background (see below).

import pygmt
from pygmt.params import Frame

fig = pygmt.Figure()
fig.basemap(region=[-2, 2, -2, 2], projection="X4c", frame=Frame(fill="darkgray"))
fig.pygmtlogo(color=False, theme="dark", width="3c")
fig.show()

With black outline	Without black outline

The outline is nice from a visual perspective, but from a consistency perspective, I prefer to remove this outline. I never really liked it, because it affects the size of the logo or the thickness of the surrounding shape.

I've remove the black outline, and also updated the baseline image with a gray background.
