snippets: add HTML snippets for library portal

- Creates a new file for custom HTML snippets.
- Adds three snippets to be used when updating the clinical medicine
  library portal with bibliographic descriptions:
  - A main HTML structure with CSS styling.
  - An item with some bibliographic description examples.
  - A list item with a link to an ebook online.
- Improves the LuaSnip configuration and moves it outside the nvim-cmp
  configuration.
