Histogram should not prepend any text to axis and hover labels (e.g. "sum of ...")

Split from #2876

We need to localize all texts in our project. So, we can't rely on auto-generated, English labels such as "sum of" or "probability."

Issue

The following code produces the correct chart. However, the auto-generated phrase "sum of" appears in the axis label and hover text.

px.histogram(
    chart_data,
    x="role_name",
    y="total_minutes",
    color="work_type",
    labels={
        # notice here the use of _("") localization function
        "role_name": _("Caregiver role"),
        "total_minutes": _("total minutes"),
        "work_type": _("Type of work"),
    },
)

Expected outcome

The desired output would be that the y-axis label and hover text would be "total minutes" rather than "sum of total minutes," the latter of which we cannot localize. Specifically, when labels are defined for chart dimensions, the aggregation type ("sum of" in this case) should not be prepended to the text, since the content and data language may not be English.

Start with the px.histogram example and its labels argument, then trace how histogram axis and hover labels are generated. Verify that localized dimension labels such as “total minutes” are shown without an automatically prepended aggregation phrase in both places.
