openjdk: Add JDK 27

[uhoefel]

Related: #607

Add support for the OpenJDK 27 GA release.

Changes

• Add bucket/openjdk27.json for the JDK 27 GA release.
• Update the rolling bucket/openjdk.json manifest to JDK 27-35.
• Change the checkver source for the current GA manifests from the JDK archive to the JDK 27 release page.

The checkver source change is necessary because JDK 27 is currently the GA release and is not yet present on jdk.java.net/archive/.

With the archive URL, the version-specific manifest cannot find JDK 27 and the rolling manifest detects the most recent archived JDK 26 release instead:

openjdk27: couldn't match ... in https://jdk.java.net/archive/
openjdk: 26.0.2.1-1 (scoop version is 27-35) autoupdate available

The existing captured variables and autoupdate URL construction are otherwise retained.
