Add timeout to contributor avatar fetch

[massy-o]

Summary

• add an explicit timeout when the contributor SVG helper downloads GitHub avatars

Why

The helper currently waits indefinitely if an avatar request stalls. A small timeout makes the maintenance script fail fast instead of hanging forever on a single contributor image.

Testing

• python3 -m py_compile shell/contributors.py

Self-review: Keeping the timeout as a named constant makes it easy to tune later and avoids leaving a maintenance script blocked indefinitely on one slow avatar response.

Code Review

This pull request introduces a timeout for network requests when fetching contributor avatars to prevent the script from hanging indefinitely. The reviewer suggested enhancing error handling by adding response.raise_for_status() to ensure the script fails explicitly on HTTP errors.

[gemini-code-assist]

While adding a timeout is a good practice to prevent the script from hanging, it's also important to ensure the request was successful before processing the response. Adding response.raise_for_status() will cause the script to fail with a clear HTTP error if the avatar download fails (e.g., 404 or 500), which is consistent with the 'fail fast' goal of this PR.

Suggested change

	response = requests.get(
	contributor["avatar_url"], timeout=REQUEST_TIMEOUT_SECONDS
	)
	response = requests.get(
	contributor["avatar_url"], timeout=REQUEST_TIMEOUT_SECONDS
	)
	response.raise_for_status()

Thanks, accepted in 1e1baef by adding response.raise_for_status() after the avatar request.
