resolves #136

This PR updates the existing filtering by tag logic in the getAllActivities service method to support an array of tags, rather than just one tag. The filter logic uses $and which will return only events with all tags in the provided tags query. If no tags are provided, the tags filter is not applied.

Applying the filtering in the back-end will allow for more control over events and pagination. Doing it this way means the user can apply a tags filter and use the "Load more events" button to load more events with the tags filter applied.

This video demonstrates

• All events returned with no tags query
• Querying events with "Professional Development" tag
• Querying events with "Social" tag
• Querying events with "Social" and "Tech" tag
• No events returned when "Social", "Tech" and "Pizza" tags were queried since I have no events in my local db that have all 3 of those tags.

I will open a PR in the front-end project to implement the UI for tags filtering once this PR is approved and merged.

I tested this PR with Postman and it looks like it's working good with single tag and multiple tag filtering.
