Thanks for this @deepyaman !

@merelcht and I have been revising the configuration docs, including this page, so if we merge this fix in first, we will be able to pull it into our changes. Nice spot! 👀

Suggested change

	From version 0.17.0, `TemplatedConfigLoader` also supports the [Jinja2](https://palletsprojects.com/p/jinja/) template engine alongside the original template syntax. Below is an example of a `catalog.yml` file that uses both features:

This is clearly longer and more cumbersome to type, but generates a cross-reference to the TemplatedConfigLoader documentation, and emits a warning in case of a typo.
