A user-facing configuration reference for RDoc covering the four configuration mechanisms (`.rdoc_options`, `RDoc::Task`, `.document`, `RDOCOPT`), a name cheat sheet flagging the nine cross-mechanism naming mismatches, and a grouped options reference with defaults sourced from `RDoc::Options#init_ivars`.

Pull request overview
Adds a new user-facing documentation page (doc/configuration.md) that consolidates RDoc configuration mechanisms and option mappings into a single reference, intended to ship as part of RDoc’s own generated documentation.
Changes:
- Documented the four configuration mechanisms (
.rdoc_options,RDoc::Task,.document,RDOCOPT) including precedence and usage guidance. - Added a “name cheat sheet” and a cross-mechanism naming table mapping CLI flags ↔ YAML keys ↔
RDoc::Taskattributes. - Added grouped option reference tables plus worked examples for common setups.
