RAMPART-454 Refresh site docs for the 2.0.0 release

- index.md: state that Rampart 2.0.0 runs on Axis2 2.0.1, requires
  OpenJDK 17 as the minimum runtime, and has been tested on OpenJDK
  21 and 25.
- release-notes/2.0.0.md: the file was carried over with 1.x-era
  dependency numbers (Axis2 1.8.2, WSS4J 3.0.3, OpenSAML 4.3.2,
  Axiom 1.4.0, BC 1.79). Rewrite against the actual 2.0.0 stack
  (Axis2 2.0.1, Axiom 2.0.0, WSS4J 4.0.1, OpenSAML 5.2.1, Santuario
  4.0.4, BC 1.83) and record the JDK 17 / 21 / 25 runtime matrix.
- site.xml: add a "2.0.0" entry under the Release Notes menu.

Existing in-code "1.8.0 and later" comments are left alone: each one
describes a behavior change that happened in 1.8.0 (e.g. "WSS4J sets
this as false however before 1.8.0 this was hard-coded to true") and
rewriting those as 2.0.0 would be historically wrong.
