feat: use lang value to translate validation report to spoken language

[rich-iannone]

This PR utilizes the lang parameter (from the Validate class) for the validation report table. This translates various elements of the reporting table (the default title, certain column headers).

With the following validation code (using lang="zh-Hant")

import pointblank as pb
import polars as pl

parquet_polars = pl.read_parquet(source="yellow_tripdata_2009-01.parquet")

validation = (
    pb.Validate(data=parquet_polars, brief=True, lang="zh-Hant")
    .col_vals_in_set(columns="vendor_name", set=["VTS", "DDS", "CMT"])
    .col_vals_lt(columns="Passenger_Count", value=1, na_pass=True)
    .col_vals_gt(
        columns=["Trip_Distance", "Fare_Amt", "surcharge", "Tip_Amt", "Tolls_Amt", "Total_Amt"],
        value=0,
        na_pass=True,
    )
    .col_vals_between(columns=["Start_Lon", "End_Lon"], left=-75, right=-73)
    .interrogate(collect_tbl_checked=False)
)

validation

We get the following localized validation report table:

With locale="de":

A locale= value can be provided to override the formatting that's taken from the lang= value.

Hey @jrycw this is that localization I was talking about before. It’s now merged and I’ll release pretty soon with this functionality!
