Fixes tcort/markdown-link-check#553

/usr/local/lib/node_modules/markdown-link-check/node_modules/markdown-link-extractor/index.js:3
const { marked } = require('marked');
                   ^

Error [ERR_REQUIRE_ESM]: require() of ES Module /usr/local/lib/node_modules/markdown-link-check/node_modules/marked/lib/marked.esm.js from /usr/local/lib/node_modules/markdown-link-check/node_modules/markdown-link-extractor/index.js not supported.
Instead change the require of marked.esm.js in /usr/local/lib/node_modules/markdown-link-check/node_modules/markdown-link-extractor/index.js to a dynamic import() which is available in all CommonJS modules.
