[someone in hewiki Administrator requests asked for...]
The link for "Know more about this feature" of Content Translation dashboard is hard-coded.
This result in:

1. Wrong link (links to redirect instead of the target link)
2. It isn't possible to config it to a language specific - e.g link to https://www.mediawiki.org/wiki/Content_translation/he instead of https://www.mediawiki.org/wiki/Content_translation

Copying from the dupe T142327:

• There is already the customizable message cx-descriptionpagelink, and it can be reused.
• This is also needed for the link in the beta feature description.
