(ruby) Bitwise OR pipe confused with Block Parenthesis pipes

**Describe the issue**
Bitwise OR operators which use pipe "|", i.e `1 | 2` get confused with block parenthesis syntax wich are two pipes, i.e.
```ruby
[1,2,3].each do |num|
# ...
end
```
Currently, anything after a pipe is forever highlighted as a parameter until another pipe appears.

**Which language seems to have the issue?**
ruby

**Are you using `highlight` or `highlightAuto`?**
Either one.

...

**Sample Code to Reproduce**
```ruby
1 | 2 # Bitwise OR
puts "between '2' and '5.times' are all hljs-params"
5.times do |num|
puts num
end
```

**Expected behavior**
Bitwise OR operator "|" should work just like any other &^~+-*/ etc.
