Set keyword value

[rouille]

Purpose

A FutureWarning is raised when running the tests:

powersimdata/design/investment/tests/test_investment_costs.py::test_calculate_gen_inv_costs_2030
  /Users/brdo/CEM/PowerSimData/powersimdata/design/investment/investment_costs.py:371: FutureWarning: The default value of regex will change from True to False in a future version. In addition, single character regular expressions will*not* be treated as literal strings when regex=True.
    cost["value"] = cost["value"].str.replace("$", "")

I have set the regex parameter to True in the replace method (current default value) to avoid any surprise when we update pandas.

Testing

No more warning when running pytest

Where to look

The optional parameter regex is set to True, which is the current default value
