Add Firestore query for group search

[haypho]

Description

Since we are only fetching a limited amount of groups from Firestore, we will need to create another query to get the search results from Firestore.

Acceptance Criteria

• Given I am a user when I type a string into the search then I should get the first 10 firebase groups that match the search
• Given I am a user when scroll down to see more groups then the filtered search text should still apply to new groups being fetched
