Rename actions (#1253)

This pull request simplifies the naming convention for GitHub Actions workflows by removing verbose descriptive text and standardizing the format. The changes make workflow names more concise while maintaining clear identification of the target platform and trigger type.

- Shortened workflow names by removing "Push to Branches" suffix
- Standardized case formatting for ARM64 architecture (ARM64 → arm64)
- Maintained descriptive suffixes only where necessary (Pull Request workflows)

Fix: #1250
