Add CI as github action. (#47)

* Add CI as github action.

Required small adjustments in build.ps1.
Also created a cron job for weekly builds.

* fix name of upload test results.

* Add skip publisher check to pester install.

* Change tests to not use PS7 commands for path combination.

Also mock PSStyle variable.

* Drop support for Windows PowerShell.

It's not possible with the use of System.Text.Json.
Add another test result file to gitignore.

* Remove mock of PSStyle variable.
