Describe the bug you're encountering

I have not tested it completely, to determine if there was any loss in functionality.

To reproduce...

Steps to reproduce the behavior:

1. docker run --rm -P swaggerapi/swagger-editor:v3.8.1
2. Open browser and point to port mapped to container port 8080
3. View docker logs
4. You'll see open() "/usr/share/nginx/html/validator.worker.js.map" failed (2: No such file or directory)

Expected behavior

No "file not found" related error message in docker logs

Screenshots

Additional context or thoughts

This is source map file, so in theory shouldn't be a problem. To fix it, I had copied the file from /usr/share/nginx/html/dist/validator.worker.js.map to /usr/share/nginx/html/validator.worker.js.map

[char0n]

After merging #2998 and building docker image locally, I can verify that this no longer manifest. It should be away when we release next version of SwaggerEditor.

Explanation:

We bundle validation worker as a BLOB URL directly to main bundle (there is no separate file). We no longer use web worker fallbacks as we expect that everybody who uses SwaggerEditor is already using a browser that supports web workers. We do declare following in our main README file: Swagger Editor works in the latest versions of Chrome, Safari, Firefox, and Edge. so we dont' consider inlining a web worker without fallback a breaking change.
