website: mention and link to #lima channel

[afbjorklund]

Description

Currently the link goes to the Slack inviter, https://slack.cncf.io/ - from https://lima-vm.io/community/

Apparently this is how you link directly to a channel: https://cloud-native.slack.com/messages/lima/

Not sure there is any difference between these two:

• Slack: Chat with other project users

• Slack: Chat with other project developers

As they would both use the #lima slack channel

This link lacks the sign-up screen.

Yes, both would probably have to be presented...

It could also be enough with a #lima next to the logo:

"+ Slack: Chat with other project users in #lima"

Anyway, I got a question about which channel to use.
