Update H3Adapter.ts use that for unjs/nitro

[Mittcio]

basePath is applied to all routes, app.use() in nuxt/nitro I think not work well

Hi thanks for the PR.
What issue do you try to solve?

[Mittcio]

I try to use that with @bull-board/nestjs which seems to auto call some of that !this.entryRoute), !this.viewPath), !this.errorHandler) and !this.uiConfig) before setBasePath
``

If use in nitrojs plugin i get 404 error

I try http://localhost:3000/api/api/b, http://localhost:3000/api/b and http://localhost:3000/b

[Mittcio]

In your example is app.use() but work with router.use like nitroApp.router.use('/**', serverAdapter.registerHandlers().handler);. But that path '/**' will cause problems it will match other routes, wil return 204 no content for some routes and other

[Mittcio]

Plus you create a second router in adapter this.uiHandler = (0, h3_1.createRouter)() but not pass existing router (created in h3 example) or not get only routes and attach its to that exisiting router (form h3 expale index.ts).

It can be .forEach({ path, handler, method }) => nitroApp.router.add(path, hadler, method)
