Use better default colors for `pyreverse`

[DudeNr33]

Current problem

The current default colors used by pyreverse when specifying --colorized are not visually pleasing and probably also not very colorblind friendly.

Desired solution

Replace the current default colors with:

[
    "dodgerblue",
    "orange",
    "teal",
    "sienna",
    "orchid",
    "lightsalmon",
    "plum",
    "gray",
    "yellow",
    "steelblue",
]
