Update space_stock_plot.py

2025-02.23.0027: fixing an issue (https://github.com/ranaroussi/yfinance/issues/2283)
which is introduced by yfinance version 0.2.54 (released on Feb 18, 2025 ).
The "Adj Close" column is missing from yf.download since yf.download default changed
from auto_adjust=False to auto_adjust=True. When auto_adjust=True, column Close is actually Adj Close and
Adj Close column does not exist any more. In order to fix the issue, auto_adjust=False is used explicitly in download function,
to get back the Adj Close column.
The "Adj Close" column is also missing from using ticker = yf.Ticker("AAPL") data = ticker.history(period="1y")
