Fix statsSync format

[ebeigarts]

Image.statsSync doesn't work with svg because image-size returns type instead of format and getFullStats expects metadata.format.

EleventyImg Skipping SVG output for './src/images/sd-logo-horizontals-rgb.svg': received raster input. +0ms

getImageSize(src)
> { height: 32, width: 118, type: 'svg' }

Config:

function imageShortcode(src, alt, cls) {
  const Image = require("@11ty/eleventy-img")
  let options = {
    widths: [null],
    formats: ["avif", "webp", "png", "svg"],
    svgShortCircuit: true,
    urlPath: `${pathPrefix}/img/`,
    outputDir: 'public/img/',
  }
  Image(src, options)
  const metadata = Image.statsSync(src, options)
  const imageAttributes = {
    alt,
    class: cls,
    loading: "lazy",
    decoding: "async",
  }
  return Image.generateHTML(metadata, imageAttributes)
}

eleventyConfig.addNunjucksShortcode("image", imageShortcode)
