pandas deprecation warning in make_results

[jack89roberts]

AIrsenal/airsenal/scripts/make_results.py:41: FutureWarning:
A value is trying to be set on a copy of a DataFrame or Series through chained
assignment using an inplace method.
The behavior will change in pandas 3.0. This inplace method will never work
because the intermediate object on which we are setting values always behaves
as a copy.
fixtures_df["home_team"].replace(teams, inplace=True)


AIrsenal/airsenal/scripts/scrape_transfermarkt.py:118: FutureWarning:
Downcasting behavior in `replace` is deprecated and will be removed in a future version.
To retain the old behavior, explicitly call `result.infer_objects(copy=False)`. To opt-in to
the future behavior, set `pd.set_option('future.no_silent_downcasting', True)`
  df = df.replace({"-": np.nan, f"? {days_name}": np.nan, "?": np.nan})
