Asset file is not found (404) if it is in a folder that contains an underscore

**Describe the bug**

Asset files are not found during fetching with javascript or accessing them through the browser when they are located in a folder that contains an underscore. The follow error is returned:
`The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.`

And the following is printed to the browser's console:
```
GET https://.westeurope.5.azurestaticapps.net/assets/app_data/data.json 404 (Not Found)
GET https://.westeurope.5.azurestaticapps.net/app_data/data.json 404 (Not Found)
```

The above behavior is observed while deploying a simple Vue3 app using SWA cli and GitHub action. The same code works fine on the local development server, and the issue only appears after deployment to SWA.

**To Reproduce**
Steps to reproduce the behavior:

With multiple `data.json` files located at the paths shown in the code below, those that are located in `*/app_data/` folder could not be retrieved.

```javascript
fetch("/data.json") --> OK
fetch("/assets/data.json") --> OK

fetch("/assets/app_data/data.json") --> 404
fetch("/app_data/data.json") --> 404

fetch("/appdata/data.json") --> OK
fetch("/app-data/data.json") --> OK
fetch("/d.a_t(a).json") --> OK
```

**Expected behavior**
The files should be accessible without a problem.
