Add workaround for .dev version parsing not semver

The strings Pulp uses, e.g. `3.17.2.dev` is not semver parsable, which
causes the semver tools to fail.

See pulp/plugin_template#682 for more info.

This should only be needed in the 'dev' site since Pulp code will only
every submit data with `.dev` at the end to the dev site.
