fix: hide INTEGER from help for count=True options (closes #1869)

Discussion: #1869

Description

Fixed #1869 — count=True options were incorrectly showing INTEGER in the help text, making it look like they take a value (e.g. --verbose 3), when they actually work as flag-like counters (e.g. --verbose --verbose).

Two small changes:

• typer/core.py: TyperOption.make_metavar() now returns "" for count=True options, matching how Click handles count internally.
• typer/rich_utils.py: _print_options_panel() now skips appending the type name (e.g. INTEGER RANGE) for count options.

Before: --verbose INTEGER [default: 0]
After: --verbose [default: 0]
