• Bump gotenberg version 8.38.1 -> 8.39.0, which includes security fixes. See the release notes.
• Upstream behaviour change: /forms/chromium/convert/url and /forms/chromium/screenshot/url return 400 for any scheme other than http and https, including chrome://, devtools:// and data:.
• Upstream behaviour change: the metadata keys j, addtagsfromfile and alltagsfromfile return 400; prefix them with a group, such as XMP:j, to write a tag of that name. ExifTool ignores ~/.ExifTool_config.
• Upstream fix: api.tlsSecretName works again. Its absolute certificate and key paths left Gotenberg not accepting connections since 8.38.0, so charts 1.26.0 to 1.29.0 are affected. A missing or unreadable file now fails the startup.
