Link to PAM Slack channel (or move user discussions to github)

[brynpickering]

Description

In the current contributing guidelines, a button for asking a question links to https://github.com/arup-group/pam/discussions

Since adding this button I realised we have a Slack channel which I believe is public, so anyone can join to ask questions. The only problem is that I can't seem to generate a public permalink for the channel. The Slack sharing links only last 14 days...

Proposed change

Either we switch this button to point at the Slack channel or we move discussions to the github page. There are advantages to both. Probably easier for now to point to the Slack channel, if a public permalink can be generated.
