update readme to reflect java 25 requirement
What changed, and why it matters
This commit simply updates documentation and a build workflow label to reflect that Sparrow now requires Java 25 instead of Java 22. It fixes a spelling mistake ('reproduciblity' to 'reproducibility') and adds an SDKMAN tip. There are no code changes and no security implications.
No security action required. Reviewers may verify that the actual build toolchain (e.g., build.gradle) is consistent with the documented Java 25 requirement, but that is outside the scope of this documentation-only commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies README.md and .github/workflows/package.yaml only. It bumps the stated Java version requirement from 22/22.0.2 to 25/25.0.2, updates the Eclipse Temurin download link, corrects a typo in a GitHub Actions step name, and adds SDKMAN guidance. No source code, dependency, cryptographic, or build logic changes are present.
