fix(ci): keep bilingual forge-announce embeds from merging

Both the DE and EN embed carried the same release url, which makes
Discord merge url-identical embeds and render only the first embed's
description. The EN block was posted and stored but never shown, so
every auto-announce from v1.4.6 onward displayed German only.

Drop the url from the EN embed so Discord stacks both as separate
cards with both descriptions visible.
