chore: bump version to 0.4.0

This also fixes some bugs with referencing figures in elements such as align,
this also generalizes the logic to handle nesting.

#__format-ref show rule now goes through #custom-ref most of the time,
so builtin #ref can be used instead.

Equations are now referenceable and respect numbering per sections.

+## Initiating the template
+Install the downloaded template under the following directory:
+- Linux: `~/.local/share/typst/packages/local/ktu-paper/0.4.0/`
+
+And then initiate a new project:
+```sh
+typst init @local/ktu-paper:0.4.0
