Security solutions cypress tests should be triggered on PRs related to alerts and actions

[ymao1]

Currently, the security solutions cypress tests are only triggered when changes occur in certain plugin paths:
https://github.com/elastic/kibana/blob/master/vars/tasks.groovy#L117-L122

However there are other plugin changes that might affect the cypress tests. It would be nice to run the tests on PRs that touch the plugins/alerts and plugins/actions paths, maybe event plugins/task_manager?

The latest example was this PR: #83578 which passed the build during the PR stage but caused immediate cypress test failures when merged into master.

Previous discussion related to this can be found here: #73939 (comment)

We just hit the same problem with a change to the data plugin #83418
