Fix container permissions for GitHub-hosted runners

Add 'options: --user root' to all container configurations to resolve EACCES permission errors when GitHub Actions tries to write to internal directories.

GitHub-hosted runners require containers to run as root to allow the Actions runtime to write to /__w/_temp/_runner_file_commands/ and other internal paths.

Affected workflows:
- build.yml (3 container jobs)
- workspace-integration-tests.yml (2 container jobs)
- ide-integration-tests.yml (2 container jobs)
- preview-env-check-regressions.yml (1 container job)
- preview-env-gc.yml (1 container job)
- jetbrains-auto-update-template.yml (1 container job)
- jetbrains-integration-test.yml (1 container job)
- code-nightly.yml (1 container job)
