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]

Hi, thanks for the contribution. Please follow the contributor guidelines and do not open issues or PRs directly. Always start with a discussion thread first. This helps us reduce AI-generated slop and maintainer's work load.

About this particular issue: open a discussion thread. I am working on related code and I can review this, but we won't be accepting user PRs as they will conflict with a refactor that is already taking place. Thanks! 🙏
