Windows paths not escaped in DevUI
### Describe the bug

On Windows when the DevUI renders the template [main.html](https://github.com/quarkusio/quarkus/blob/91ba39965d13652e853446e227b256a1b8cea477/extensions/vertx-http/deployment/src/main/resources/dev-templates/main.html) the path are not properly escaped leading to the page not being able to be used as JavaScript is broken.

The code [here](https://github.com/quarkusio/quarkus/blob/91ba39965d13652e853446e227b256a1b8cea477/extensions/vertx-http/deployment/src/main/resources/dev-templates/main.html#L146-L150) takes the paths as is and put them into the HTML, leading to the following error `provider:594 Uncaught SyntaxError: Invalid Unicode escape sequence (at provider:594:70)`.

### Expected behavior

The paths should be properly escaped using `\\\\` for path separators on Windows.

### Actual behavior

It lead to the JavaScript error:
`provider:594 Uncaught SyntaxError: Invalid Unicode escape sequence (at provider:594:70)`

### How to Reproduce?

Create/move a project into a path where the directory would start with an invalid Unicode character i.e. `c:\\userproject`.

I have created and uploaded a sample project to Github as a sample:
https://github.com/bwolkerstorfer/sample-quarkus-path-issue

Steps:
1. run the project on Windows using `gradle quarkusDev`
2. navigate to i.e. http://localhost:8080/q/dev/io.quarkus.quarkus-oidc/provider
3. check the JS console
