Describe the bug you're encountering

After installation, the dist folder contains the following files:

.../swagger-ui/node_modules/swagger-ui/dist$ ls -1
oauth2-redirect.html
swagger-ui.css
swagger-ui.css.map
swagger-ui.js
swagger-ui.js.map
swagger-ui-standalone-preset.js
swagger-ui-standalone-preset.js.map

As we learn from the installation documentation:

The module's contents mirrors the dist folder you see in the Git repository. The most useful file is swagger-ui-bundle.js, which is a build of Swagger-UI that includes all the code it needs to run in one file.

However these (essential!) files are missing.

index.html
swagger-ui-bundle.js
swagger-ui-bundle.js.map

After wgetting the raw versions from the Git repo everything is working fine.

To reproduce...

Steps to reproduce the behavior:

1. npm install swagger-ui
2. Go to node_modules/swagger-ui/dist
3. ls
4. See missing files :(

Expected behavior

The files

index.html
swagger-ui-bundle.js
swagger-ui-bundle.js.map

ought to be there.

Additional context or thoughts

( ... how can this happen at all in the age of sturdy development pipelines? )

Start by installing swagger-ui version 3.23.0 with npm and inspecting the generated node_modules/swagger-ui/dist directory. Compare its contents with the documented files and the repository's dist assets, including index.html and the swagger-ui-bundle.js files. Done means the expected files are included after installation.
