Experiment with sb & dependencies upgrade

[ndelangen]

I'm attempting to reduce the incompatibility of this package when combined within a repository that already contains storybook.

What Changed

This PR telescopes on PR where this work has been done:

• Upgrade eslint to latest (needed for SB10
• Modify eslint config files to adhere to latest version
• Formatting changes due to eslint upgrades
• Upgrade typescript to latest (needed for SB10)
• Change tsconfig to use moduleResolution:bundler (needed for SB10)
• Removed source map generation
• Disabled minification
• Use node 22 in GitHub actions (SB10 does not support Node18)
• upgrade cypress (to support moduleResolution:bundler)
• replace jest with vitest

This PR itself, now only contains the following changes:

• Upgrade storybook to latest
• Remove addon-essentials ( no longer exists in SB10)
• Change local addon using '.' to direct references to manager and preview files in main.* files.
• regenerate lockfile
• make the main, preview and manager files ESM

@ndelangen thanks for taking this on!

It looks like there are a lot of cascading changes in this PR (to upgrade SB to 10, we need eslint upgraded; also we need Cypress upgraded to 15 for the same reason, Node needs to be upgraded, etc).

If this PR is opened just to be able to publish canary versions (and will later be split up before it's out of draft state), no worries.

If this PR is intended to be merged in its current format, I'd prefer to split this up into a few separate PRs (Cypress to 15, eslint upgraded, then SB to 10) to keep things manageable and avoid regressions.

@ndelangen thanks for this! See my couple comments below, but I don't need to re-review before you merge this.
