Remove dependency to date_recur [#3582858]

Problem/Motivation

Can't install the module without date_recur. With my understanding of how this works this doesn't require date_recur as this leverages smart_date and it's recur submodule.

Proposed resolution

Remove date_recur as a dependency in the info.yml

Issue fork smart_date_recur_search_api-3582858
