Opening Remote from the Welcome Screen "Recent" is not case sensitive

Type: Bug

• Setup a remote in .ssh/config with mixed casing (e.g. "AppBuilder")
• Connect to this remote with the Remote Explorer
• Try to connect to this remote from Welcome Screen -> Recent
• The remote can not be reached
  The problem is caused by the ssh invocation, which is lowercasing the remotes name:

[08:10:53.832] Running script with connection command: "C:\Program Files\OpenSSH\ssh.exe" -T -D 5712 appbuilder bash

The remote can be reached from the remote explorer, as it builds the commandline with correct casing:

[08:21:18.812] Running script with connection command: "C:\Program Files\OpenSSH\ssh.exe" -T -D 1073 "AppBuilder" bash

Trace how the Welcome Screen's Recent action constructs the SSH connection command, and compare it with the Remote Explorer path described in the report. Reproduce the failure with a mixed-case host such as "AppBuilder"; done means both paths preserve the configured casing and connect successfully.
