fix(entities): toolbar create button size

[Leopoldthecoder]

Summary

This PR uses useActionOutside to decide the size of the create entity button in the toolbar, so that:

1. the create entity button size aligns with the learning hub icon in Gateway Manager
2. the create entity button size aligns with the column toggle icon in Kong Manager

This PR also removes use-action-outside on EntityBaseTable because EntityBaseTable does not have this prop.

On a second thought, should we move the <Teleport> into EntityBaseTable and make the use-action-outside prop just work, instead of duplicating <Teleport> everywhere?
