Added snowflake driver to CLI

[nvoxland]

Impact

• Bug fix (non-breaking change which fixes expected existing functionality)
• Enhancement/New feature (adds functionality without impacting existing logic)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

Now that we ship snowflake support without needing an extension, we are adding the driver as a shipped dependency to make it easier for everyone using snowflake.

Things to be aware of

• Adds snowflake-jdbc.jar to internal/lib
• Should not be adding any additional jar files vs. what was in internal/lib before
• Version shows in liquibase --version
• Should now be able to run liquibase against snowflake without having to add anything to the lib dir
• Also removes the snowflake extension from the extension release list

Things to worry about

• Nothing

On this PR, the only new driver in internal/lib dir is snowflake-jdbc.jar. Also it is not in the extention release list anymore.
