error running `./bw-dev site:compile`

[Hugh Rundle]

Looks like this wants a metadata file in /images/ - I think maybe we need to exclude this directory in get_site_data?

  File ".../documentation/generate.py", line 145, in <module>
    data = get_site_data(SLUG, locale["code"], content_path)
  File ".../documentation/generate.py", line 67, in get_site_data
    with open(f"{cat_dir}/_meta.yml", "r", encoding="utf-8") as meta_yaml:
FileNotFoundError: [Errno 2] No such file or directory: 'content/images//_meta.yml'
