[BUG][typescript] Schema format `uri` produces invalid TypeScript

The following spec uses schema format uri.

openapi: 3.0.1
info:
  title: Foo
  description: Bar
  version: "2"
paths:
  /foo:
    get:
      parameters:
        - name: bar
          in: query
          schema:
            type: string
            format: uri
      responses:
        "200":
          description: Ok

The generated TypeScript project contains file apis/DefaultApi.ts which references a non existing URI module like this:

import { URI } from '../models/URI';

For some reason the generator expects a URI type. However, it doesn't create this reference for other custom formats. If the formt is set to i.e. bar then the expected type is string and everything works fine. The format value uri seems to be somewhat special.

I'm using generator version v5.4.0.

Reproduce the issue with the supplied OpenAPI document and generator version v5.4.0, then inspect the generated apis/DefaultApi.ts and the TypeScript generator's handling of the uri format. Compare it with a custom format such as bar. Done means the generated project no longer references a nonexistent models/URI module and the output remains valid TypeScript.
