Adding 2022-07-19 variant (#18156)
Diff between `20220617-variant-a` and `20220719-variant-a` (e.g. the new
incumbent with minor tweaks):
```

< "description": "Blend of 20220603-variant-b and 20220603-variant-a",
---
> "description": "Copy of 20220617-variant-a with tweak to negative privileged user",
84,85c84,85
< "negative_reaction_threshold": -10,
< "positive_reaction_threshold": 10
---
> "negative_reaction_threshold": -9,
> "positive_reaction_threshold": 4
```
**Note**: In the above I'm adjusting the `negative_reaction_threshold`
and `positive_reaction_threshold` to reflect the value of the privileged
user reaction points:
```ruby
class Reaction < ApplicationRecord
BASE_POINTS = {
"vomit" => -50.0,
"thumbsup" => 5.0,
"thumbsdown" => -10.0
}.freeze
```
See the [current state of app/models/reaction.rb](817db3e6f8/app/models/reaction.rb (L1-L6))
Further, the thresholds are exclusive (e.g. `<` or `>` not `<=` or `>=`).
Diff between `20220719-variant-a` (e.g. the new incumbent) and
`20220719-variant-b` (e.g. the challenger)
