[APPS-45767] Let an external browser callback be provided to use, supports Snowflake VS Code Extension SSO

[sfc-gh-klin]

We've been patching this for 1.5 years on our end. Without it, there are SSO problems when customers login, since the VS Code API has an API to openExternal: https://code.visualstudio.com/api/references/vscode-api (search for openExternal) that controls how browser windows open from extensions.

Can we have this officially inside the node connector?
