Allow ```:``` in the user for ssh connection

[cfouche3005]

Describe the bug I use a selfhosted service called Warpgate for managing user and ssh connection behind NAT. Warpgate format user in a special way to allow access control and forwarding. It format the ssh user like this : user:host@warpgate.redacted. Wave doesn't allows : in the ssh form so I cannot use Warpgate with Wave.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Connexions'
2. Try to add a connexion with a : in the user
3. See error

Expected behavior The connexion should be added and can be used with Wave

Desktop (please complete the following information):

• OS: Linux x64
• Version : 7.6

Additional context : is supported by regular ssh client like openssh or termius

I second the desire for this enhancement. It would be a game changer with the ability to store commands on workspaces per connection.
