fix: remove button from Gradio event handler inputs in benchmark selector (#4553)

* fix: remove button from Gradio event handler inputs in benchmark selector

`_update_value` and `_update_variant` used gr.Button as an input to read
its label, but Gradio doesn't reliably pass button values causing
"didn't receive enough input values" errors (~340 occurrences in logs).

Seems like label is already in scope so no input is needed. Tested locally and everything worked fine (and couldn't get it to re-appear), but I am not 100% sure on this change.

* Update mteb/leaderboard/benchmark_selector.py
