[Sync] Update project files from source repository (ead8752)

[mrz1836]

What Changed

• Updated MAGE_X_VERSION from v1.13.0 to v1.15.0 in .github/.env.base
• Updated MAGE_X_GORELEASER_VERSION from v2.13.1 to v2.13.2 in .github/.env.base
• Updated MAGE_X_YAMLFMT_VERSION from v0.20.0 to v0.21.0 in .github/.env.base
• Added new MAGE_X_BENCHSTAT_VERSION configuration set to v0.0.0-20251208221838-04cf7a2dca90 in .github/.env.base
• Updated comments in .gitpod.yml to use more generic project descriptions instead of specific project names
• Added new GitHub Action setup-benchstat for setting up benchmark statistics tooling
• Added new GitHub Action upload-statistics for uploading build and test statistics
• Updated documentation files to reflect new MAGE-X features and tooling capabilities
• Modified several workflow files to include permissions configurations and updated step descriptions

Why It Was Necessary

• Upgrading to MAGE-X v1.15.0 brings newer build tooling capabilities and improvements
• Adding benchstat support enables standardized benchmark analysis and performance tracking across CI/CD pipelines
• Updating dependency versions (goreleaser, yamlfmt) ensures access to latest bug fixes and features
• Genericizing Gitpod configuration comments makes the setup more reusable across different projects

Testing Performed

• Verified that all version numbers reference valid releases from their respective repositories
• Confirmed that the new benchstat action configuration follows GitHub Actions schema standards
• Validated that workflow permission changes align with GitHub's least-privilege security model
• Ensured documentation updates accurately reflect the new tooling capabilities

Impact / Risk

• Low Risk: Version updates are incremental and maintain backward compatibility
• Performance: Addition of benchstat tooling enables better performance monitoring without affecting runtime behavior
• CI/CD: New actions and workflow changes may require validation in actual CI runs to ensure proper integration
• No Breaking Changes: All modifications are additive or version bumps that maintain existing functionality
