Subject: [PATCH] Remove useless condition in example

## Motivation and Context

The example files `examples/http_client.rb` and `examples/streamable_http_client.rb` are
intended to be run as standalone scripts and are not designed to be reused as modules (e.g., via `require`).
The `if __FILE__ == $PROGRAM_NAME` guard therefore serves no purpose and is removed.

## How Has This Been Tested?

Manually verified that each example script can still be executed directly
(`ruby examples/http_client.rb`, `ruby examples/streamable_http_client.rb`).
No automated tests cover files under `examples/`.

## Breaking Changes

None. The files under `examples/` are standalone scripts and are not part of the gem's public API.
