swift-cmark dependency not available for 5.8 RELEASE

[sebsto]

Description
When building Swift 5.8 with the swift-installer-script, the build fails because version 5.8 and 5.8.1 for Swift cmark GFM is unavailable.

Downloading: https://github.com/apple/swift-cmark/archive/swift-5.8.1-RELEASE-gfm.tar.gz#/swift-cmark-gfm.tar.gz
Download failed:
404 Client Error: Not Found for url: https://codeload.github.com/apple/swift-cmark/tar.gz/swift-5.8.1-RELEASE-gfm#/swift-cmark-gfm.tar.gz

Trying manually, I found out that 5.7 version is available.

Should we remove this dependency from 5.8.x and more recent ? Or produce a 5.8 binary package of Swift cmark GFM?

Steps to reproduce
Run build_rpm.sh script for Amazon Linux 2 and Swift 5.8

Expected behavior
Build should succeed.

Environment
Amazon Linux 2

I just managed to compile Swift 5.8 without using Swift cmark GFM.
I guess this dependency is not used anymore by Swift >= 5.8
I close this issue but I would love someone reply with an authoritative answer
