fix(reddit): remove unreachable 429 check after raise_for_status()

[priya-sundaram-dev]

Addresses the genuine bug @cclauss flagged in #15174 (web_programming/reddit.py).

response.raise_for_status()
ifresponse.status_code==429:
raisehttpx.HTTPError(response=response)

Two problems with the removed lines:

1. Unreachable.response.raise_for_status() already raises httpx.HTTPStatusError for every 4xx/5xx response, including 429, so the following if response.status_code == 429 can never be true — execution never reaches it.
2. The dead call was itself invalid.httpx.HTTPError.__init__(self, message) takes a message string and has no response parameter, so httpx.HTTPError(response=response) would raise TypeError if it ever ran. (This is exactly the unknown-argument / missing-argument diagnostic ty reports on this file.)

The fix keeps raise_for_status() — the intended rate-limit behaviour is preserved — and drops the dead branch, with a short comment explaining why no extra status check is needed. The __main__ note about Error 429 still applies.
