This is a follow-up to commit 9c5e5ca1c0.
The previous package was called “ghc-x” which is not available on Stackage,
instead change it to “ghc-pandoc” which does exist, and adjust its version.
* tests/lint.scm ("haskell-stackage"): Add additional metadata for the
package; change package name to “ghc-pandoc”; and change to version to
“100.0”.
