NIT: The new substring check "com.amazon.deequ:deequ:1" in DEEQU_MAVEN_COORD is less precise than the original regex intent. It would match a hypothetical version like com.amazon.deequ:deequ:12.0.0-spark-3.5 (a future major version starting with '1' but not actually v1.x). A more robust fix for the deprecation warning would be to either use a raw string with the original regex (re.search(r"com\.amazon\.deequ:deequ:1\.", DEEQU_MAVEN_COORD)) or check for ":deequ:1." (with trailing dot) to ensure it's actually version 1.x.

Line 44: IS_DEEQU_V1 = "com.amazon.deequ:deequ:1" in DEEQU_MAVEN_COORD — this matches any string containing the substring, including potential future versions like deequ:10.x or deequ:12.x. The original regex com\.amazon\.deequ\:deequ\:1.* was anchored to version strings starting with '1'. Looking at SPARK_TO_DEEQU_COORD_MAPPING (lines 7-11), current values are all deequ:2.0.8-spark-*, so this is not a current bug, but it's a correctness regression for future-proofing.
