How to get access to Slack after Broadcom switch

[Smithx10]

I'm trying to join the slack, what are the instructions to get an invite?

The project encourages the community to collaborate using GitHub [issues](https://github.com/vmware/govmomi/issues), GitHub [discussions](https://github.com/vmware/govmomi/discussions), and [Slack](https://vmwarecode.slack.com/messages/govmomi).

Note Access to Slack requires a free [VMware {code}](https://developer.vmware.com/join/) developer program membership.

It didn't get much use even before the switch and Slack is gone now for us. Update the doc: https://github.com/vmware/govmomi/blob/main/README.md#discussion
