Deprecated locale.format() in indicator.py

[Peter Kokot]

System: Ubuntu: 24.04

The locale.format() function has been deprecated in Python 3.7 and removed in 3.12. Instead locale.format_string() can be used in the indicator.py file by a simple rename. Otherwise this error occurs when launching indicator-cpufreq:

Traceback (most recent call last):
  File "/usr/bin/indicator-cpufreq", line 85, in <module>
    ind = MyIndicator(options.show_frequency)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/indicator_cpufreq/indicator.py", line 78, in __init__
    menu_item = Gtk.RadioMenuItem.new_with_label(group, readable_frequency(freq))
                                                        ^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/indicator_cpufreq/indicator.py", line 34, in readable_frequency
    label = _("%s GHz") % locale.format(_("%.2f"), f / 1.0e6)
                          ^^^^^^^^^^^^^
AttributeError: module 'locale' has no attribute 'format'. Did you mean: '_format'?

Status changed to 'Confirmed' because the bug affects multiple users.

replacing 'format' with '_format' fixes the problem

although it is recommended to replace 'locale.format' with 'locale.format_string'. Also works but is safer.
