Update gradle version, fix flaky integration tests, and add cleanup job (#197)

## Problem

1. Integration tests have been failing 
2.
[submit-gradle](https://github.com/pinecone-io/pinecone-java-client/actions/runs/18015820954/job/51260319239?pr=197#logs)
job was failing because it used java 21 with incompatible gradle
version.

## Solution

1. Fix flaky integration tests
2. Add cleanup job that deletes all indexes after integration tests are
completed (regardless of success/failure of the job)
3. Update gradle version to 8.5 for all workflows

## Type of Change

- [x] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] This change requires a documentation update
- [ ] Infrastructure change (CI configs, etc)
- [ ] Non-code change (docs, etc)
- [ ] None of the above: (explain here)

## Test Plan

Integration tests should run successfully
