removed skipping tests using tags as this isn't functional. cannot
apply tags to stories made using addon-svelte-csf. therefore cannot
skip intermittently passing tests.
instead all tests will be rerun upto 9 times if any tests fail. A
better approach would be rerunning individual tests but this would
require a PR for test-runner.
add dependancies to enable tests to run
there is a slight missmatch in html classes in `js.snap` test vectors
when tests are run with storybook is built using `storybook dev` vs
`storybook build`
