Upgrade markmap to 0.14.x

[jawspeak]

Upgrading to be able to take advantage of newer features in markmap. https://markmap.js.org/

This has no new functionality and no changes, it just upgrades the markmap dependency. A follow up PR may then have new functionality such as setting expanded levels in the mind map.

EDIT - the below is now fixed also in the 2nd commit.

Note before and after this PR I was seeing the following issue when running npm run dev (using nvm ``)

Errors/warnings on master:

bundles src/main.ts → dist...

The second commit fixes the warning by using the recommended updated api. (layout-ready was removed, so I updated it with the new mechanism.)

@lynchjames hopefully this is acceptable to merge, and can get out for everyone's benefit! Same as #103 too! Thanks,
