Is it also a requirement that we need to add a link back to the Apache Airflow page?

Yes, it is required. Thank you!

@pankajastro I'm unsure about this change, I think there is a high likelihood we'll forget adding this symbol after every mention to Apache Airflow.

Also, dbt is equally registered as a trademark: https://www.getdbt.com/assets/docs/dbtTrademarkGuidelines.pdf

And probably other technologies we're mentioning in the docs as well, including Databricks and Snowflake. Is this change really necessary?

I checked the dbt trademark guidelines, and the documentation advises using dbt™. Does this mean it is not a registered trademark?
I couldn't find any sources for Databricks and Snowflake that provide guidelines on how to use their names correctly.

@pankajastro Fair enough, let's make our docs compliant with Apache Airflow® - this is the scope of this PR - and when we learn more about the other projects, we can update the docs. Thanks a lot for checking this, @pankajastro !
