The hasura console cli to reuse same tab if already open

### Is your proposal related to a problem?

When you start `hasura console` it always opens in a new tab so I end up having multiple tabs that bloats my browser. I have a monorepo with multiple packages starting up from one command. I want the console to start a tab but I don't want a new instance every time I restart my project.

### Describe the solution you'd like

In node community we use a module called to prevent such thing: https://www.npmjs.com/package/better-opn. There is probably something similar in go that you can use.

### Describe alternatives you've considered

The only solution right is now is to:
`hasura console --no-browser && node custom-made-better-open.js`

Start with the `hasura console` CLI behavior and its `--no-browser` option; compare the requested reuse behavior with the `better-opn` module referenced in the issue and investigate the corresponding Go browser-opening support. Done means repeated console starts reuse an already open tab instead of creating another, while `--no-browser` still avoids opening one.
