Debug -> Open Web Profiler silently fails in some Linux environments

[pewsplosions]

Describe the bug (REQUIRED)
Selecting Debug -> Open Web Profiler does nothing. Tried while running from Project -> Build and Debug -> Start/Attach both with same results.

To Reproduce (REQUIRED)
Steps to reproduce the behavior:

1. Start project with Project -> Build.
2. Click Debug -> Open Web Profiler.
3. Wait for nothing to happen?

Expected behavior (REQUIRED)
Expecting the web profiler to open in the default web browser.

Defold version (REQUIRED):

• Version 1.4.8

Platforms (REQUIRED):

• Platforms: Linux
• OS: Linux (Kubuntu 23.04)
• Device: Desktop (Default browser set to Firefox)

Workaround (OPTIONAL):
The in-app overlay profiler works fine. May also be able to manually enter the URL into the web browser but not real sure what that URL would be.

Additional context (OPTIONAL):
This is likely specific to local environment conditions. It also generates no related logs. Opening web links from applications on Linux distros in general are hit or miss. After discussing with @britzl on Discord, it was suggested to make this issue: "We should try to work around it and at the least let the user know about it."

A potentially easy, non-fix, but informative option may be to print to console or pop up something that has the URL the editor just tried to open with the 'Open Web Profiler' click. This way even if nothing happens the user could copy/paste that into their browser (assuming it works that way.)

Could it be that the OS for some reason doesn't indicate that the java.awt.Desktop.Action.BROWSE is supported. Perhaps there is not default browser set?

I no longer have a Linux PC to check this out with but I do know other apps that would open a browser link, for the most part, worked fine at the time. It was admittedly a little hit or miss (like the Additional Context says.) There was a default set though for sure.

I have the same issue and figured out workaround: https://forum.defold.com/t/solved-can-not-open-web-profiler/76212
