Dark mode is not recognized in PlotHistory in tslib

[hrntsm]

Description

I noticed while creating the PR #1054 that DarkMode is not recognized in the rendering in tslib.

The following PlotHistroy part refers to plotlyDarkTemplate in tslib, but I assume this is because colorTheme refers to DarkColorTemplates in optuna_dashboard.

optuna-dashboard/tslib/react/src/components/PlotHistory.tsx

Line 435 in 88ab123

color: colorTheme === plotlyDarkTemplate ? "#666666" : "#cccccc",

optuna-dashboard/optuna_dashboard/ts/components/PlotlyColorTemplates.ts

Line 8 in 88ab123

If I make the above plotlyDark refer to the one in tslib, this problem will be solved, is this solution ok?

How to Reproduce

1. Perform constrained optimization
2. Check the color of the INFEASIBLE marker for dark mode with constraints in plots such as history, the color is #cccccc when not in dark mode.
