@krol3 I see spelling checks are failing for Spanish words, perhaps we need to update the tests to include Spanish or how can we add words to the vocabulary?

Excelente trabajo, @mlunadia, tan solo una sugerencias de estilo (que estoy consolidando en un documento).

Sobre los errores de spelling, el diccionario no es del todo completo. Sugiero añadir las excepciones en el frontmatter usandp cSpell:ignore: o bien a https://github.com/open-telemetry/opentelemetry.io/blob/main/.cspell/es-palabras.txt

Gracias @theletterf por las sugerencias!
