[signing] Sigin: Offer manual fallback in case the extension can't open a browser

[geropl]

Description

Addresses an issue I see when trying to signin with cursor (appimage, on Linux):

1. Stays in "Signing in" for 60s and then fails
   • 
2. Logs read:

2025-01-28 17:36:24.236 [info] Logging in for the following scopes: function:deleteWorkspace function:getLoggedInUser function:getOwnerToken function:getSSHPublicKeys function:getWorkspace function:getWorkspaces function:sendHeartBeat function:startWorkspace function:stopWorkspace resource:default
2025-01-28 17:37:31.686 [error] Failed to load session: Cancelled
2025-01-28 17:37:31.686 [error] Failed to sign in

The idea here is to show a warning if openExternal returns false (hope that is the right signal).

@geropl you can test by going to the Run and Debug tab of VS Code and hitting play: that should open up a new VS Code window with the debug extension activated.

I've just tried by manually changing vscode.env.openExternal to just be false: signing in with the manually-copied URL worked flawlessly!

Awesome, then let's merge 😜

Is the release process automated, or do we need to "nudge" it somewhere? 🤔

@geropl seems like ESLint is complaining about you using " instead of ' for strings. I took the liberty to push a fix

AFAIK it's automated for the pre-release channel, but it requires a manual publish (IIRC a manual GitHub Action run) to do a latest release

Whoops, seems it might have missed your commit. Let me create a new PR

No, it's all in. Nice.

@geropl actually looks ok, the main commit this got merged into has my single quote fixes in it: 2ffe187
