chore: move esbuild to devDependency

[teemingc]

splitting up some of the changes in #13427 into separate PRs

This PR moves esbuild to a dev dep since we no longer use it during build to bundle the server into a single worker file, we only use it to bundle worktop into the worker before we publish the package. This also removes the @types/ws from the dev deps since it's not in use and may have been added accidentally?

• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.
