Update dep & fix vulnerabilities

[timea-solid]

• updated prod dependencies to newest

• updated eslint from version 8 to 9 -> migration of config file (see: https://eslint.org/docs/latest/use/configure/migration-guide) which includes:
  ** drop for standard because outdated, now using neostandard
  ** drop for node because discontinued, now using n.

• typescript from 4.x to 5.x

• jest from 27.x to 30.x with jsdom and jest-environment-test )skipped 2 tests because of too many Jest workers (needs fix sometime)

• didn't manage to update nock because I get errors like 'ReferenceError: TransformStream is not defined'

• didn't manage to update @testing-library/user-event" because tests give different results

• updated babel
  ** babel proposal dep deprecated -> updated to transform

• updated webpack, especially cli to 6.x

• only updated Storybook from 6.x to 7.x (8 is not possible due to the usage of MDX stories, which is not supported anymore from 8). I created a separate issue for a future upgrade.

• react is also dependent on storybook and only needed for it.

P.s. if build fails on publish -> not a concern
