trivial: Fix HACKING.rst nits causing rendering issues

Currently the HACKING.rst documentation is published here:
https://docs.openstack.org/patrole/latest/HACKING.html

And it is apparent that underneath the [0] section that
some of the hacking checks are incorrectly formatted
like [T109]. This fixes those issues.

     The original Tempest Commandments do not include Patrole-specific paths.
     Patrole-specific paths replace the Tempest-specific paths within Patrole's
     hacking checks.

 The following are Patrole's specific Commandments:
 
 - [P100] The ``rbac_rule_validation.action`` decorator must be applied to
-         an RBAC test
+  an RBAC test
 - [P101] RBAC test filenames must end with "_rbac.py"; for example,
-         test_servers_rbac.py, not test_servers.py
+  test_servers_rbac.py, not test_servers.py
 - [P102] RBAC test class names must end in 'RbacTest'
 - [P103] ``self.client`` must not be used as a client alias; this allows for
-         code that is more maintainable and easier to read
+  code that is more maintainable and easier to read
