module EarmarkParse is not available or is yet to be defined

Pulled this in to a clean phoenix app tonight and going through the setup instructions I was getting an error:

== Compilation error in file lib/<redacted>/router.ex ==
** (UndefinedFunctionError) function EarmarkParser.as_ast/2 is undefined (module EarmarkParser is not available)
    EarmarkParser.as_ast("\n", [gfm: true, gfm_tables: true, file: "priv/pages/hello.md", breaks: false, sub_sup: true, wikilinks: true, pure_links: true, footnotes: true, code_class_prefix: nil])

    (elixir 1.16.0) lib/kernel/parallel_compiler.ex:428: anonymous fn/5 in Kernel.ParallelCompiler.spawn_workers/8
Compiling 1 file (.ex)

when running mix.deps.compile it made things a bit clearer:

==> phoenix_pages
Compiling 1 file (.ex)

adjusting the call in phoenix-pages/lib/phoenix_pages/markdown.ex on line 43 from

case EarmarkParser.as_ast(contents, parser_opts) do

to

case Earmark.Parser.as_ast(contents, parser_opts) do

seemed to fix things for me
