feat(error-detection): add multiple pattern support

[theakshaypant]

📝 Description of the Change

Add support for configuring multiple error detection regex patterns at both global (ConfigMap) and repository (CR) levels. This allows users to match different error formats from various linters and tools in a single pipeline.

Global Configuration (ConfigMap):

• Changed error-detection-simple-regexp to support arrays
• Supports 3 formats: single pattern (backward compatible), multi-line YAML, and JSON array

Repository CR:

• Added ErrorDetectionSettings with patterns array and max_number_of_lines
• Patterns are additive with global patterns
• Per-repository max_number_of_lines override
