Added applyAfterQueryCallbacks to non-mutator case in pluck

[batinmustu]

This change adds the applyAfterQueryCallbacks call to the non-mutator case in the pluck function.
With this update ensures that pluck behaves consistently across mutator and non-mutator scenarios, improving code reliability.

Reasons for Change

When using the "pluck" method, the "afterQuery" method was not working when a column without a mutator was given.

I am closing this pull request because it lacks sufficient explanation, tests, or both. It is difficult for us to merge pull requests without these things because the change may introduce breaking changes to the framework.

Feel free to re-submit your change with a thorough explanation of the feature and tests - integration tests are preferred over unit tests. Please include it's benefit to end users; the reasons it does not break any existing features; how it makes building web applications easier, etc.

Thanks!
