Battery history and statistics graphs markings are unreadable on a dark theme

[Rahul Jaisheel]

1 - Use a dark theme using Gnome Tweaks.
2 - Open Power Statistics
3 - Click on Laptop battery -> History or Statistics tab.

The markings on the X and Y axes are not readable since the text colour does not adapt to the dark theme.

We can see a changed color of legend labels with modification of fixed color values.
It should be get from theme color instead of fixed value.
