The change in e404c311 broke models that
relied on single-type inheritance:

```
CommitStatus.new(type: 'Ci::Build').class
=> Ci::Build

CommitStatus.new.tap{|c| c.assign_attributes(type: 'Ci::Build')}.class
=> CommitStatus
```

As a result, any serialized options would not be properly saved to the
database, leading to errors expecting a `Hash` vs. a `String`, for
example.

This affected all pipelines that used shared runners because the build
would error out due to this serialization error.

Use the correct equality operator for Prometheus Alerts

See merge request gitlab-org/gitlab!18919

- Prometheus uses == (not =) for equality. Alerts that use single
  equal (=) result in a syntax error that silently fails to
