add title parameter for the angular axis of polar charts

As the title says, the title of the angular axis can't be changed or set as a parameter. I can change the radial axis title, but not the angular one. There is also no parameter in the documentation https://plotly.com/python/reference/layout/polar/#layout-polar-angularaxis. The code for the redefinition of my chart is below.

chart_result.update_layout(
        polar = dict(
            sector=[0, 180],
            angularaxis=dict(
                #thetaunit = "degrees",
                dtick=10,
                #rotation=270,
                direction="counterclockwise",
                #tickmode="array",
                tickvals=list_angular_ticks,
                ticktext=list_angular_labels,
            ),
        ),
        height=600
    )
    
    chart_result.update_polars(
        radialaxis_title_text='Normalized STD',
    )

I also have a proposal for the placement of the title. As seen in the code below, I will only consider the upper half of a circle. Therefore, the title could be placed in the middle - at 90 degrees (above the tick labels). This is also valid if we have, for example, only one quadrant (0-90). In that case, the label should be placed above 45 degrees tick label. An example can be seen below. This logic also works for other domains.

Start with the angularaxis configuration and the polar-chart reference documentation at the linked layout/polar/angularaxis page. Define how an angular-axis title should be exposed and positioned for sectors such as 0–180 and 0–90, then verify that the title can be set alongside the existing radial-axis title and that the documentation describes the parameter.
