fix: fix storybook build cache not being used by tests in CI (#5451)

TL;DR:
- removed `--configuration={args.scope}` from `storybook:static:test`
for the `storybook:static` part, as it was making `front-sb-test` jobs
in CI not reuse the cache from the `front-sb-build` job and re-build
storybook every time.
- replaced it with a new `test` configuration which optimizes storybook
build for tests and builds storybook 2x faster.

## Fix storybook:build cache usage in CI

`storybook:static:test` executes two scripts in parallel:
1. `storybook:static`, which depends on `storybook:build`
1.a. it builds storybook first with `storybook:build`, the output
directory is `storybook-static`.
1.b. then it launches an `http-server`, using what has been built in
`storybook-static`
2. `storybook:test` to execute tests (needs the storybook http-server to
be running)

When passing `--configuration=pages` or `--configuration=modules` to
`storybook:static` from step 1, those configurations are passed to the
`storybook:build` script from step 1.a as well.

But for Nx `storybook:build` and `storybook:build --configuration=pages`
(or `modules`) are not the same command, therefore one does not reuse
the cache of the other because they could output completely different
things.

As `front-sb-test` jobs are passing `--configuration={args.scope}` to
`storybook:static`, the cache of the previously executed
`storybook:build` (from `front-sb-build`) is not reused and therefore
each job re-builds Storybook with its own scope, which increases CI
time.

### Solution

- Removed scope configurations from `storybook:static` and
`storybook:build` scripts to avoid confusion.
- `storybook:test` and `storybook:dev` can keep scope configurations as
they can be useful and this doesn't impact storybook build cache in CI.

### Improve Storybook build time for testing

Added the `test` configuration to `storybook:build` and
`storybook:static` which makes Storybook build time 2x faster. It
disables addons that slow down build time and are not used in tests.
