[powershell]: Fix manual PowerShell installation binary execution p…

…ermissions (#1050)

* Align manual pwsh install with DEB package

- ensure execution permissions for pwsh
- correct path from /usr/local/bin/pwsh to /usr/bin/pwsh
- register as shell in /etc/shells

* Update versions

* Update repositories

* Check for existing pwsh installation

This will avoid build failures when multiple features depend on this PowerShell package

* test: Fix PS profile test

* Test: Fix install_using_github

* Test: Fix getcwd warning

* fix: Move out of directory before deleting it

* test: Add validate_powershell_installation

* test: Change Ubuntu test base image to upcoming new LTS version
