Update docs to reflect that Antora no longer skips examples and partials without a file extension
The hidden and unpublished files section on standard file and directory set page still states that Antora ignores files that don't have an extension. As of Antora 3, there's a new exception to this rule. The file extension is not required for files in the example and partial directories.
https://docs.antora.org/antora/3.0/standard-directories/#hidden-files
The exception is as follows:
Only catalog extensionless files located in the example or partial family
