SFTP notifications have wrong icons

[tyuldashev]

Description
Messages about creation of sftp config file and copying project to the server has warning icons while should be info ones

To Reproduce
Steps to reproduce the behavior:

1. Complete 'UTBot: Quick setup wizards'

Actual behavior
After server configuration if everything completed successfully then couple notifications shown, both have orange triangle as in icons

Expected behavior
They have 'info' icons - blue circles as on image below:

Additional context
I also think that exclamation sign at the end of these sentences is not necessary.
Probably there are other info messages from SFTP configuration which are also have wrong icons.
