[PATCH] Remove value::copy call from gdbpy_get_varobj_pretty_printer

[PATCH] Remove value::copy call from gdbpy_get_varobj_pretty_printer

[Tom Tromey]

I noticed a call to value::copy in gdbpy_get_varobj_pretty_printer,
and I couldn't figure out why it was there.  I think maybe it came
from the time when value_to_value_object would release values from the
value chain -- but that was removed in commit f3d3bbbc.

This patch removes this call.  Regression tested on x86-64 Fedora 36.

I'm checking this in.
