Remove pip install termcolor from spring pipelines for network isolation

[rujche]

Description

termcolor is only used in sdk/spring/scripts/log.py, which already falls back gracefully via try/except ImportError when termcolor is absent. Removing the install avoids external PyPI access under the upcoming CI network isolation policy (PyPI access failure).

Pull request overview

This pull request removes python -m pip install termcolor steps from Spring CI/pipeline YAMLs to avoid external PyPI access under upcoming CI network isolation, relying on the existing sdk/spring/scripts/log.py graceful fallback when termcolor is unavailable.

Changes:

• Removed pip install termcolor from Spring monitor pipeline job templates.
• Removed pip install termcolor from Spring compatibility test pipeline job templates.
• Kept Python logging behavior intact by relying on existing try/except ImportError fallback in sdk/spring/scripts/log.py (verified: only usage of termcolor under sdk/spring).
