chore(glossy): release version 0.4.0

## New features:

**Articles with `a`/`an` modifier**

Now you can include articles using this new modifier. The articles may
be defined in your dictionary entry (fields `artcile`, and
`longarticle`). But, if you don't define them, Glossy will do a
reasonably good job at guessing them.

This modifier is also allowed before the term. For example, you might
have this term:

```yaml
www: Worldwide Web
```

And you could display it with an article by any of these:

```typst
@a:www
@an:www
@www:a
@www:an
```

These, `a` and `an` are exactly equivalent. They're just provided for
your convenience. Use either or both.

The `a`/`an` modifier works with all modifiers except `pl` and
`def`/`desc`.

If you want to define custom articles for your terms, do so like this:

```typst
#let glossary = (
  rf: (
    short: "RF",
    article: "an",
    long: "radio frequency",
    longarticle: "a",
  )
  uts: (
    short: "UTS",
    article: "a",
    long: "untranslatable string",
    longarticle: "an",
  )
)
```

But again, in most cases (for English) you shouldn't need to because
Glossy should usually get it right.

Fixes [#12](https://github.com/swaits/typst-collection/issues/12).

## Other changes:

- added test which exhausts all reference options
- added panic if 'def'/'desc' used when no `description` field exists
- significantly improved the (English) pluralizer function
- `__gls()` function refactored, cleaned up
- removed a rogue PDF
