[FIX] Storage class selector not working

[eva-vashkevich]

Summary

Fixes : #12971
As part of Vue 3 migration, we needed to remove @input from compponents that use LabeledSelect

Occurred changes and/or fixed issues

Fixed event listener in StorageClassSelector.
I've checked and other LabeledSelects should be fine (there is a PR for Node Scheduling already). We also have components that are listening for 'search' event, which is not declared on LabeledSelect, but it seems to work and I think will require more investigation.

Technical notes summary

Areas or cases that should be tested

1. Create a new StorageClass
2. Apps -> Charts -> Monitoring -> Install/Update -> Prometheus -> Persistent Storage for Prometheus -> Storage Class name -> You should be able to select a storage class
3. Apps -> Charts -> Monitoring -> Install/Update -> Grafana -> "Enable with PVC Template" Grafana storage -> Storage Class name -> You should be able to select a storage class

Areas which could experience regressions

None
