Rest API - Organization - Search By Keyword

[Code4SocialGood]

• Rest API
  GET /api/organizations/search (already exist)

• Requirement

1. In organization table, add a column: project_updated_time, timestamp, not null

2. Searches the keyword in organization name and description, case insensitive.

3. The search result is sorted by project update time in descending order. Sorting by project update timestamp ranks the most active organizations on top of research result.

4. Add the following comments to the endpoint operation (serve as Javadoc):
   Searches the keyword in organization name and description, case insensitive. The search result is sorted by project update time in descending order.
