Snowflake connector: Fix required to enable air.check.skip-enforcer (set `air.check.skip-enforcer` to `false`)

[dmariamgeorge]

As per the comment #4 (comment):

In connectors/presto/presto-snowflake/pom.xml, setting air.check.skip-enforcer to false, is throwing the following errors:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M2:enforce (default) on project presto-snowflake: Execution default of goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M2:enforce failed.: NullPointerException.

When downgrading the Snowflake JDBC Driver jar version, the error is resolved. But the particular version is having a vulnerability. Hence this approach can't be adopted, and need to analyse further to address the issue.
