Normalize includes paths using same rules as other helpers

This means that nested directories are no longer supported, as you should use a data collection for that. See https://github.com/hydephp/develop/pull/1738/files#r1655369910

@@ -25,6 +25,7 @@ This serves two purposes:
 - Minor: Changed the default build task message to make it more concise in https://github.com/hydephp/develop/pull/1659
 - Minor: Data collection files are now validated for syntax errors during discovery in https://github.com/hydephp/develop/pull/1732
 - Minor: Methods in the `Includes` facade now return `HtmlString` objects instead of `string` in https://github.com/hydephp/develop/pull/1738. For more information, see below.
+- Minor: `Includes::path()` and  `Includes::get()` methods now normalizes paths to be basenames to match the behaviour of the other include methods in https://github.com/hydephp/develop/pull/1738. This means that nested directories are no longer supported, as you should use a data collection for that.
 - The `hasFeature` method on the Hyde facade and HydeKernel now only accepts a Feature enum value instead of a string for its parameter.
 - Changed how the documentation search is generated, to be an `InMemoryPage` instead of a post-build task.
 - Media asset files are now copied using the new build task instead of the deprecated `BuildService::transferMediaAssets()` method.
