[2.x] Remove experimental annotations from codebase

[emmadesilva]

Removed various @experimental comments and annotations from documentation, configuration, and source files to reflect stabilization of features and APIs. Updated documentation to indicate 'basic' rather than 'experimental' support for Blade front matter. No functional code changes were made. This is because either these changes are now stable after being experimental for a while, or because we are committing to them for the v2 release.
