The configuration file for Zola is named config.toml.
TOML files can be validated using JSON schemas through tools such as the Even Better TOML extension in Visual Studio Code.
To facilitate creating a schema for Zola configuration and upload it to a public registry such as the JSON Schema Store, a distinguishable filename should be used for this file.
Thus, I propose changing the configuration filename for future releases of Zola. My suggestions are zola.config.toml or zola.toml.
