Doesn't work for title who are solely content

[ice1000]

Say if I have a file like

= #smallcaps[114514]

This will make the following code from lib.typ crash:

error: type none has no method `trim`
    ┌─ C:\Users\ice10\git-repos\website\templates\page.typ:123:40
    │
123 │         let title = plain-text(it.body).trim();
    │                                         ^^^^

A similar function is provided in https://github.com/typst/typst/issues/2196#issuecomment-1728135476

It has type content...

The "to_string" implementation is actually already in our template.

#let title = plain-text(it.body).trim();

🤔This is for making hash string labels (hashtags) for headings.

                                            ^^^^^^^^^^^^^^^^^^^

We can give up on providing hashtags if plain-text whatever returns none.

But I'm also interested in whether we can have a more robust approach to create hash strings, at least for simple content such as #smallcaps[114514].

Yeah that would be great

The "to_string" implementation is actually already in our template.

But lib.typ will be overwritten by the compiler, so it's immutable in a sense
