[ES3][Connectors]Using EuiComboBox with searchable capability as we d…

…o in ESS (elastic#199464) ## Summary This PR swaps the `EuiSelectable` by the `EuiComboBox` component as we have in ESS. ### Context: This PR belongs to this initiative elastic/search-team#8000 where we agreed on bring low hanging fruit artefacts from ESS to ES3 before being replace completly with the full new experience which will be later. Therefor we are not investing effort on make the code scalable and reusable at this point. ![CleanShot 2024-11-08 at 12 59 47](https://github.com/user-attachments/assets/a73884c2-7ea4-412c-a5de-386003733d0a) --------- Co-authored-by: Elastic Machine <[email protected]> Co-authored-by: Navarone Feekery <[email protected]> Co-authored-by: kibanamachine <[email protected]> Co-authored-by: Rodney Norris <[email protected]>
