Add AsciiDoc snippet for CI/CD Badges

This commit adds CI/CD Badges Snippets for AsciiDoc as requested in #26087.
I've however run into an issue in highlighting the snippet, it seems as if AsciiDoc is currently not being highlighted properly (displayed as plaintext)

Add testcase for to_asciidoc

Update test case for Badges list
