Remove channel and clustered recs experiments #5822

Ticket(s) / Related Merge Requests

#5822 (closed)

Summary of Changes

• Removed wrapper that only showed channel recommendations in the channel feed if the flag was on. Now it should always show on other users' empty channel feeds (i.e. no post has been made by the channel)
• Changed conditions for when the default feed loads the clustered recs endpoint api/v3/newsfeed/feed/clustered-recommendations (instead of default feed endpoint api/v3/newsfeed/default-feed). Previously it needed a location input AND experiment enabled. Now it just needs a location input to show clustered recs. Note there is only one scenario where the location input is used -- discovery top feed.
• Found extra padding in guest mode default feed when testing, removed it

Testing Considerations

• discovery top feed
• channel feed
• guest mode default feed (it should NOT be using the clustered recs endpoint)

Deployment Considerations

1. Merge in tandem with engine!1186 (merged)

2. Delete minds-2263-clustered-recs and minds-2933-channelrecs from growthbook once merged
