Closing bracket highlighted in red if block has more than 5 arguments

[Sayrus]

Name of the lexer When a block has more than 5 arguments, the closing bracket is highlighted in red.

Code sample A sample of the code that produces the bug.

block {
  a = true
  b = true
  c = true
  d = true
  e = true
  f = true
}

block {
  a = true
  b = true
  c = true
  d = true
  e = true
}

resource "test" "test" {
  a = true
  b = true
  c = true
  d = true
  e = true
  f = true
}

  trying: #<Rule //>
    got: ""
    yielding: Text, ""
    popping stack: 1
    warning: too many scans without consuming the string!
    no match, yielding Error

The reason is that it recurse inside :composite for each additional property. Leading to the scanner reach }\n and popping all the :composite.

Stack before popping them:

stack: [:root, :hash, :composite, :composite, :composite, :composite, :composite, :composite]

The reason why it fails after that is because MAX_NULL_SCANS = 5. So the number of arguments is limited by the stack it reaches why recursing into :composite.
