Example 1-3 for typst fails because of relative paths

[rpapallas]

Following the instructions in README for example_1 for typst fails. If you open chapters/introduction/introduction.typ and you attempt to create a new figure in there, you will get the following code:

#figure(
  image("figures/test2.svg", width: 80%),
  caption: [caption]
) <label>

but the path is relative and when you try to compile, it will fail with the following error:

  ┌─ chapters/introduction/objectives.typ:8:8
  │
8 │   image("figures/test2.svg", width: 80%),
  │         ^^^^^^^^^^^^^^^^^^^
