QMarkdown extension missing dependencies

[auriorx]

Describe the bug
Adding the QMarkdown@next extension and running quasar dev leads to missing markdown-it components.

To Reproduce
Steps to reproduce the behavior:

1. Run quasar upgrade -i
2. Run quasar ext add @quasar/qmarkdown@next
3. Run quasar dev
4. Returns errors for markdown-it-* subcomponents like: UnhandledPromiseRejectionWarning: Error: Cannot find module 'markdown-it-footnote

Expected behavior
I would expect quasar dev to work after running quasar ext add @quasar/qmarkdown

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

Workaround
I've manually added the following packages to make it work:

yarn add markdown-it-emoji
yarn add markdown-it-sub
yarn add markdown-it-sup
yarn add markdown-it-footnote
yarn add markdown-it-deflist
yarn add markdown-it-abbr
yarn add markdown-it-ins
yarn add markdown-it-mark
yarn add markdown-it-task-lists

Any user also experiencing this issue could use the code above to manually insert the missing packages quickly.

Please see release notes, specifically breaking changes, in the last release: https://github.com/quasarframework/quasar-ui-qmarkdown/releases/tag/v2.0.0-alpha.7

It looks like the app-extension itself was missed as it converts markdown at build time for imported *.md files.

This is fixed in v2.0.0-alpha.8
