[🐛 Bug]: When branches contain a slash in them, the build process fails since images cannot be tagged with a slash.

[jamesmortensen]

What happened?

In the build process, we use the branch name as the version. If the branch name has a slash in it, such as "pulls/20", then the following error occurs:

error: invalid tag "seleniarm/base:pull/20-today": invalid reference format

We could fix this in the circleci/config.yml file by replacing slashes in the branch name with dashes, or by using the Selenium version number instead of the branch name.

Command used to start Selenium Grid with Docker

Any commits to a branch starts the [Seleniarm CircleCI build and test jobs](https://app.circleci.com/pipelines/github/seleniumhq-community/docker-seleniarm).
