Add discord widget to trial instances

[malomarrec]

We want to have a way for users of cloud trial (and possibly cloud) instances to chat with us. We evaluated several options: Intercom, an in-product widget, a link to discord, using our existing widget. There are three criteria: dev-friendliness, privacy and security, and effort to implement and maintain. We decided on the following:

• Add a link to discord from instances, that looks like a widget but is just a link to our Discord that opens in a new tab. We'll do this immediately as there is no security or privacy implications. The link will be to a #cloud-trial channel, with a notice at the top that "This is a public channel, contact us at trials@sourcegraph.com or DM xxx if you need to share private information".
• Investigate if we can have discord running in-page, like here. If it's possible, have that run in www.sourcegraph.com/discord-trials to make it so users don't have to have a discord account to chat with us.

Plan-

• Before the December release:
  • [ ] Define and add a metric for widget utilisation cc @danielmarquespt @ebrodymoore
  • [ ] Design where the "widget" will be located @danielmarquespt
  • [ ] Run this by @rafax to understand if this should only be in PLG-trials or on all cloud instances
  • [x] Ask @jdorfman to create a #cloud-trials channel, and set the description
  • [ ] Add the "widget" to cloud trial instances. When a user clicks on it, it opens in a new tab.
• After
  • [ ] Investigate making it so anonymous users can post

@jdorfman "This is a public channel for discussing cloud trials. If you need help in a private conversation, email us at ce-team@sourcegraph.com". Does that work?

[jdorfman]

@malomarrec perfect. Updated

Hey @malomarrec, this issue didn't have a team label. Given you created it, I assigned you and added your team label. Feel free to unassign yourself. If this is not the right label, can you make sure to add the right one?

@danielmarquespt @erzhtor any change we can this in before the December release?

We need designs first, but event if the design is ready, I don't think that we can finish this by that time, because the December release is on Monday, the 12th.
