User strings were used as-is in certain parts since they were taken directly from `info.yaml`, but this could sometimes cause the datasheet build to fail since they've found a way (intentionally or not) to escape the content box that they were in.
This commit attempts to address this issue by:
- Sanitising user input using regex
- Using Typst's `str()` function instead of content boxes where possible
- Clarifying syntax in certain sections
Hopefully these changes will remove (or at least reduce) the chances of someone breaking the build.
