### Bug description

When using CrossRef autocomplete feature for references in VSCode I get this error.

```
Error running filter /Applications/quarto/share/filters/crossref/crossref.lua:
/Applications/quarto/share/filters/crossref/crossref.lua:3448: attempt to call a nil value (global 'init_crossref_options')
stack traceback:
[Error - 01:36:53] Request textDocument/completion failed.
  Message: Request textDocument/completion failed with message: Command failed: /Applications/quarto/bin/tools/pandoc --defaults defaults.yml
Error running filter /Applications/quarto/share/filters/crossref/crossref.lua:

stack traceback:

  Code: -32603 
```

I guess the bug is caused by a function naming inconsistency in the release version of v1.3.427.

[crossref.lua](https://github.com/quarto-dev/quarto-cli/blob/1412f03797ca3446cec67d190b8dbd66fff8e5f5/src/resources/filters/crossref/crossref.lua)

```lua
-- chain of filters
return {
  init_crossref_options(),
  ...
}
```

[options.lua](https://github.com/quarto-dev/quarto-cli/blob/1412f03797ca3446cec67d190b8dbd66fff8e5f5/src/resources/filters/crossref/options.lua)

```lua
function initCrossrefOptions()
  return {
    Meta = function(meta)
      crossref.options = readFilterOptions(meta, "crossref")

      -- automatically set maxHeading to 1 if we are in chapters mode, otherwise set to max (7)
      if crossrefOption("chapters", false) then
        crossref.maxHeading = 1
      else
        crossref.maxHeading = 7
      end

    end
  }
end
```

The `main` branch is not affected by this issue, only the current release (v1.3) branch.

### Steps to reproduce

1. Use current Quarto version (v1.3.427)
2. Try to use VSCode Intellisense in .qmd file, that tries to lookup a [reference](https://quarto.org/docs/authoring/cross-references.html#references)

### Expected behavior

Autocomplete works and no error is shown.

### Actual behavior

Autocomplete doesn't work and an error is shown in the output.

### Your environment

- IDE: Visual Studio Code 1.79.2
- OS: MacOS Ventura 13.4
