Remark Preset Obsidian

Remark preset to recreate Obsidian-flavored markdown.

Includes existing plugins like:

• remark-gfm (Github-flavored markdown)
• remark-frontmatter
• remark-math
• remark-wiki-link

And introduces a new plugin:

• remark-highlight (to add support for highlighted text with the ==syntax==)

And it introduces support for something close to obsidian-citation-plugin

• remark-cite
• remark-bibliography (which adds a bibliography section based on pandoc-style citations, e.g., [@hoogland2022])
