feat(nuxt): Add _experimental.useDiagnosticsChannelInjection

[s1gr1d]

Adds the useDiagnosticsChannelInjection option and updates the E2E test.

When using _experimental.useDiagnosticsChannelInjection, users also need to do those steps:

1. Call Sentry.experimentalUseDiagnosticsChannelInjection() just before Sentry.init()
2. Remove --import ./.output/server/sentry.server.config.mjs from your startscript
3. Add sentry.autoInjectServerSentry: 'top-level-import' in nuxt.config.ts so Sentry's server configuration is automatically imported

Bug: The @sentry/server-utils package is pinned to 10.65.0 in packages/nuxt/package.json, while new code depends on APIs from version 10.66.0, causing a build failure.
_{Severity: HIGH}

Suggested Fix

In packages/nuxt/package.json, update the version of @sentry/server-utils from 10.65.0 to 10.66.0 to align with other Sentry packages and provide the necessary APIs for the new experimental feature.

Potential issue: The `packages/nuxt/package.json` file incorrectly pins the
`@sentry/server-utils` dependency to version `10.65.0`, while all other Sentry packages
in the same file are at `10.66.0`. New experimental code for diagnostics channel
injection, enabled via `_experimental.useDiagnosticsChannelInjection`, imports APIs like
`INSTRUMENTED_MODULE_NAMES` from `@sentry/server-utils`. These APIs were introduced in
version `10.66.0`. Due to the version mismatch, attempting to use this new feature will
cause a build failure because the required exports are not present in version `10.65.0`.
