Add markdown files to prettier ignore list

After configuring prettier to use an indent of four spaces for Markdown
files it is adding a four space indent after the "-" character in
bulleted lists (see prettier/prettier#5019).
For now configure prettier to ignore Markdown files altogether to avoid
incorrect formatting changes.
