Show agent startup script when connecting to a Workspace

[EhabY]

New Approach

In case the template has a blocking script, then we should wait for the script to finish executing and show the user the progress as it's happening. This will make it clear that something is happening and there are no network issues instead of thinking it's just stuck.

Old Approach

This will show the agent startup script logs and provide much better feedback to the waiting user than what we show by default.

In the VS Code extension, we support 4 Remote SSH extensions:

• ms-vscode-remote.remote-ssh -> opensshremotes.showLog
• jeanp413.open-remote-ssh -> opensshremotes.showLog
• codeium.windsurf-remote-openssh -> windsurf-remote-openssh.showLog
• anysphere.remote-ssh -> opensshremotes.showLog~~

Since they are never installed together we can just execute all of them and ignore any errors (best effort approach)
