Add AVIF support to GD.

[mlander]

AVIF is picking up support(https://caniuse.com/avif) across most major browsers, so it would be great if we can get support in lando.

I did try to enable AVIF in GD following: https://php.watch/versions/8.1/gd-avif

I was trying:

      - apt-get update -y
      - apt install libavif-dev libaom-dev libdav1d-dev -y
      - docker-php-ext-configure gd --enable-gd --with-freetype --with-jpeg --with-webp --with-avif
      - docker-php-ext-install gd

(Unsure if ibaom-dev libdav1d-dev are actually necessary`)

Which shows:

However, I'm still getting errors around missing codec Could not encode image: No codec available in Command line code on line 1. From what I've found so far, it may require an upgrade to Debian 12(Bookworm).
