fix(alert): 'View Alert Rules' now preserves the project from settings. (#20842)

Previously when clicking View Alert Rules on the settings page, the user would be redirected to the alert rule page with the project shown being preserved from global selection. This can cause users to click on View Alert Rules from settings and then view the alert rules from a completely separate project.

This code adds the project query parameter into the url to override global selection.
