Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Avoid propTypes and defaultProps in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Avoid using ../ in import paths. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'

Why aren't these URLs using the "help URL" API? We just did some refactoring of it in #2714 which is why I'm thinking about it, but it seems to be doing the exact same thing.

@bradenmacdonald Not sure about that, we didn't introduced those links, i just took the work to wrap hardcoded links with that new function. Coming from this thread: https://openedx.slack.com/archives/C04BM6YC7A6/p1764789053939589?thread_ts=1763672859.489199&cid=C04BM6YC7A6

LGTM. Just one 404 issue to fix and then I think this is good.

[bradenmacdonald]

This docs URL was working before, but now seems to be a 404. Can we first replace it with a working URL? Perhaps https://docs.openedx.org/en/latest/educators/concepts/advanced_features/about_content_experiments.html ?

i think is this one 🤔 https://docs.openedx.org/en/latest/educators/references/course_development/parent_child_components.html

Nice work on this! The implementation is clean and consistent across all components. Documentation is thorough and will be helpful for operators wanting to customize external links. Consider adding a note in the docs that the URL list may be incomplete/is a snapshot in time. I also left an unrelated comment about a className typo, maybe we can fix it with this PR?

I ran grep to verify you've caught all the user-facing external documentation links and it looks like you caught everything. Everything else in the codebase is test mocks, code comments, or dynamic URLs.

Once the broken link is fixed (per @bradenmacdonald's comment), this should be good to merge!

[bradenmacdonald]

@diana-villalvazo-wgu Please fix the test that needs to be updated, and then I can merge.
