docs: printk-formats: fix build warning

Add an empty line after the '::' starting the code block so that the
following lines are properly interpreted.

Without this, the following build warnings are visible.

Documentation/core-api/printk-formats.rst:136: WARNING: Unexpected indentation.
Documentation/core-api/printk-formats.rst:137: WARNING: Block quote ends without a blank line; unexpected unindent.
