fix: add aria-label to NcSelect

[enjeck]

It's good for accessibility if the NcSelect component has an aria-label. Plus, this fixes the error in the console:

Console Error

vue.runtime.esm.js:4625 [Vue warn]: [NcSelect] An `inputLabel` or `ariaLabelCombobox` should be set. If an external label is used, `labelOutside` should be set to `true`. found in ---> at src/shared/components/ncTable/sections/CustomTable.vue at src/shared/components/ncTable/NcTable.vue at src/modules/main/partials/TableView.vue at src/modules/main/sections/DataTable.vue at src/modules/main/sections/TableWrapper.vue at src/pages/Context.vue at src/App.vue

I guess we also want a backport? :)

/backport to stable0.7

The backport to stable0.7 failed. Please do this backport manually.

# Switch to the target branch and update it
git checkout stable0.7

We don't have pagination in stable 0.7, so can't backport this
