Docs build in google-cloud-build fails with Bullet list ends without a blank line; unexpected unindent

[parthea]

See build log here which shows the docs build failure with error message Enumerated list ends without a blank line; unexpected unindent.. The issue is that lines in some list items are not indented. The list exists here , but it is not indented properly in the generated output here. For example, see this error below

sphinx.errors.SphinxWarning: /usr/local/google/home/partheniou/git/python-cloudbuild/google/cloud/devtools/cloudbuild_v1/types/cloudbuild.py:docstring of google.cloud.devtools.cloudbuild_v1.types.cloudbuild.BuildTrigger:40:Bullet list ends without a blank line; unexpected unindent.

We have

        name (str):
            User-assigned name of the trigger. Must be
            unique within the project. Trigger names must
            meet the following requirements:

            + They must contain only alphanumeric characters
            and dashes. + They can be 1-64 characters long.
            + They must begin and end with an alphanumeric
            character.

but sphinx expects the text in the list items to be indented like this

        name (str):
            User-assigned name of the trigger. Must be
            unique within the project. Trigger names must
            meet the following requirements:

            + They must contain only alphanumeric characters
              and dashes. 
            + They can be 1-64 characters long.
            + They must begin and end with an alphanumeric
              character.

I manually fixed the docs build in googleapis/python-cloudbuild@e22d641 to unblock the owlbot PR googleapis/python-cloudbuild#421. I'll start working on a fix in the generator.
