feat: Add support for image scaling via markdown

[oldmartijntje]

Adds #625.

With this change, you can select the width of an image like ![300](link) and ![alt text|300](link). This is a feature from obsidian syntax.

See below an image of the feature.

This is the markdown that was used to create this above example:

![64](https://docs.oldmartijntje.nl/000-Files/image/Temmie_Sprite.webp)

![TEMMIEEEE|64](https://docs.oldmartijntje.nl/000-Files/image/Temmie_Sprite.webp)

![32](https://docs.oldmartijntje.nl/000-Files/image/Temmie_Sprite.webp)

![TEMMIEEEE|32](https://docs.oldmartijntje.nl/000-Files/image/Temmie_Sprite.webp)

![TEMMIEEEE](https://docs.oldmartijntje.nl/000-Files/image/Temmie_Sprite.webp)

When a user does ![300](link) instead of ![alt text|300](link), the alt text of an image will be empty, cause it does not seem logical to keep the width as alt text.

See the dev-tools of the above example:

@saberzero1 for the wikilink parser I have this implemented already, but for current Quartz we can also merge this one.

We should probably freeze development on v4 soon.

V5 is in the works?? Can we test/use it?
