chore(tests): moved fixtures to testdata

[petruki]

This pull request primarily updates the Go version used throughout the project, upgrades GitHub Actions dependencies, and reorganizes test snapshot data. The most significant changes include bumping the default Go version, updating CI dependencies, and moving test snapshot files to a new location. These changes improve consistency, keep dependencies up-to-date, and help organize test data more effectively.

CI/CD and Dependency Updates:

• Updated the default Go version from 1.26.3 to 1.26.4 in all workflow files (master.yml, sonar.yml, and staging.yml) and matrix configurations. [1] [2] [3] [4]
• Upgraded GitHub Actions dependencies: actions/github-script from v8 to v9 and sonarsource/sonarqube-scan-action from v8.1.0 to v8.2.0 in workflow files. [1] [2] [3]

Test Snapshot Data Reorganization:

• Moved snapshot test data from the tests/snapshots directory to testdata/snapshots, updating all relevant test code and helper functions to reference the new path. [1] [2] [3]
• Added a new testdata/snapshots/default.json file and removed the old tests/snapshots/default.json, ensuring test data is now under testdata as per Go conventions. [1] [2]
