Merge introduction to Dev #77

	---
	# This workflow lints the SOPs within the 'sops/' directory.
	# The logic of this workflow is:
	# - Details: ZH-268
	# - Why: helps maintain consistency of SOPs, both in format and content
	# - Would block the PR if failed? If the mode is not strict, all errors
	# should be addressed before merging with 'main'
	# - How: calls the linter class 'SOPLinter' within 'sop_linter.py'
