fix(brew): update homebrew asset link to include v

[marcneubauer]

brew install wundergraph/wundergraph/wunderctl is broken, and returns the following error:

==> Fetching wundergraph/wundergraph/wunderctl
==> Downloading https://github.com/wundergraph/wundergraph/releases/download/0.176.2/wunderctl_0.176.2_Da
curl: (22) The requested URL returned error: 404

Error: wunderctl: Failed to download resource "wunderctl"
Download failed: https://github.com/wundergraph/wundergraph/releases/download/0.176.2/wunderctl_0.176.2_Darwin_arm64.tar.gz

This is because the string template for the URL to the asset in .github/goreleaser/.goreleaser-darwin.yml:127 is missing a 'v' after '/releases/downloads/' in the link.
Link from github releases:

https://github.com/wundergraph/wundergraph/releases/download/v0.176.2/wunderctl_0.176.2_Darwin_arm64.tar.gz
                                                           --^---

Also related but closed- wundergraph/homebrew-wundergraph#1
