LabeledSelect: Filter $attrs applied to v-select

[rak-phillip]

Summary

This filters the attrs that have already been applied to the wrapper div of LabeledSelect so that they don't get applied to the inner v-select.

This duplicate application was causing additional classes like mr-10 & in-input to be applied to both the wrapper div and v-select, causing visual regressions when custom classes were applied.

Fixes #11954

Occurred changes and/or fixed issues

• Filter attrs to be applied to v-select in LabeledSelect.vue
