feat!: Remove deprecated parameters in Series.cut/qcut and update struct field names

[stinodego]

Ref #13525

Changes

• Removed the break_point_label, category_label, and as_series parameters from Series.cut/qcut
• Updated the default struct names from brk and {name}_bin to breakpoint and category
• Similarly, updated hist col name from break_point to breakpoint

These are unstable functions, so this is technically not breaking. But let's include it in the "breaking" category of the changelog to make it easier to find for people.
