Describe the workflow you want to enable

The current diagram truly hurts eyes when everything else in dark mode. It would be a very nice feature to add.

Describe your proposed solution

Currently I do it this way, but I bet there could have been a better way.

`
def display_dark(pipeline, text_color="#3bd5eb"):
replacements = {
"color: black": f"color: {text_color};",
"background-color: white": "background-color: transparent",
'class="sk-toggleable__label sk-toggleable__label-arrow"': 'class="sk-toggleable__label sk-toggleable__label-arrow" style="background-color: #222831;"',
"#696969;": "#e6e6e6;",
"#d4ebff;": "#1a1a1a;",
"background-color: #f0f8ff;": "background-color: #393e46",
"background-color: #d4ebff;": "background-color: #1a1a1a;",
"color: #e6e6e6;": "color: #b3b3b3;"
}

html = estimator_html_repr(pipeline)

for old, new in replacements.items():
    html = html.replace(old, new)
display(HTML(html))

`
