fix: remove node: prefix from import statement for webpack + nuxt bridge

[kyumoon]

I am currently developing in a 'bridge + webpack' environment and found an error while trying to integrate ofetch in advance for migration.
The error is the same as the issue reported in the bridge repository below.
From what I have identified, imports with the 'node:' prefix do not work properly and need to be removed for the 'webpack + bridge' environment to function correctly.

issue: nuxt/bridge#1066 ( bridge )
reproduction: https://github.com/kyumoon/nuxt-birdge-example/tree/test/ofetch

node: protocol is supported in all stable Node.js versions and ofetch targets modern runtimes/syntax.

Please raise an issue in nuxt bridge, to support node: protocol 🙏🏼
