cli: --retryTagFilter case inconsistent with other args #1291
Description
To specify a tag filter for retry:
$ cucumber-js --retryTagFilter @flaky
It being in camel case is inconsistent with others like format-options, world-parameters and require-module which are kebab-case.
This is not just aesthetic, as it means if you are using something like dargs to create profile strings on the fly, you can't rely on a consistent rule.
Suggest we change it to --retry-tag-filter - we could potentially keep the camel cased one as an alias for one major release cycle and make it output a warning for now? cc @charlierudolph
