[Suggestion] Slack theme

[alvaropinot]

Hi 👋, after joining your Slack as I like to quickly visualize my different Slacks, I couldn't help my self and I created a custom Slack theme following the Brand Style Guide, it looks like this 👇 . Hope you like it 😅

NOTE: The header, or Menu BG and the items gets royal when hovered as in the picture, is deep royal or coral otherwise.

Here 👇 the custom values for the theme, ready to copy paste in Slack menu bar settings 😃.

#400D9A,#8719CB,#F89C30,#FFFFFF,#8719CB,#FFFFFF,#29BFF2,#D024C6

If this was done already, just ignore and close this issue 😅. If you are interested I'll PR back to this repo.

I like it!
I wonder if it could be also documented in our guide:
Maybe in https://github.com/src-d/guide/blob/master/communication/slack_channels.md

Also, I wonder if it can be defined as a welcome message in Slack, because if pasted #400D9A,#8719CB,#F89C30,#FFFFFF,#8719CB,#FFFFFF,#29BFF2,#D024C6
into a new message, it let's you to change the theme easily,

e.g.

Welcome to source{d} Community.
To enjoy the full experience, you can use our custom Slack Theme clicking in "switch sidebar theme" :point_down::skin-tone-2:

#400D9A,#8719CB,#F89C30,#FFFFFF,#8719CB,#FFFFFF,#29BFF2,#D024C6

will produce:
