Fix extremely minor typo in docker-run man page

[briantracy]

The latin phrase "vice versa" can be pronounced "vice-a-versa", but should not be rendered as such.

- What I did

Fixed an extremely minor typo in the docker-run man page.

- How I did it

Made a 6 character edit to the docker-run markdown documentation page.

- How to verify it

First, check out the definition of vice versa. Then note the definition of vice-a-versa indicates that it is a "phonetic alternate spelling". This irks the extremely pedantic as the original latin phrase can be kept intact.

Now, while my one semester of college linguistics taught me that there is no "right" way to pronounce something, and that the fluidity of language is not only to be expected, but should not have a moral value ascribed to it, I think that if the original phrase is both remembered and widely used, we should defer to that.

- Description for the changelog

Fixed an extremely minor typo in the docker-run man page.
