Remove padding from item containers

[itaikta]

This instead can be set in the style given to the itemContainerStyle (it doesn't seem to override for me)
It may also be worth checking to see other values in the hard coded styles that the module user can't change

Can we get this approved and merged?? It would be a welcomed changed, given the fact that it would allow the height of the item container to be modified.

While this would work, I'd suggest merging both the supplied style & the default one, to allow for an "overwrite"?

[programmrz]

any update on this?

@itaikta — handled this differently in the maintained fork @carlos3g/element-dropdown (v2.13.0): the default item padding stays for back-compat, but it's now overridable via itemContainerStyle. Closes #322 / #251 / #266 / #250 / #203 / #187 functionally without breaking existing layouts.
