Using debugPort with a socket path does not seem to work with a relative path.

Hello, this issue is related to ruby/debug#982.

Since the autogenerated socket name was too long, I decided to use a local socket path:

{
    "type": "rdbg",
    "name": "Attach with rdbg",
    "request": "attach",
    "debugPort": "tmp/rdbg.sock",
}

However with this in conjunction with RUBY_DEBUG_OPEN=true RUBY_DEBUG_SOCK_PATH=tmp/rdbg.sock rails s, I'm always the following error when trying to Attach to the started process.

I would have expected the config to look up the file relative to the workspace root directory? Using an absolute path to the same folder works: "debugPort": "/Users/louis-michel.couture/work/my_project/tmp/rdbg.sock",.

I also tried:

• "debugPort": "./tmp/rdbg.sock",
• "debugPort": "../tmp/rdbg.sock", thinking it was maybe relative to the launch.json location.
  But both of those didn't work.

Although we supported a relative path in the socket path, you can write as follows:

"debugPort": "${workspaceFolder}/foo.sock"

@ono-max thanks!
