Watson 1667c1180e Use start_with? and end_with? to detect SQUARE_BRAKET ...

## Test code
```ruby
require 'benchmark/ips'

SQUARE_BRACKETED = /\A\[(.*)\]\z/m
markup = "[product.catchall]"

Benchmark.ips do |x|
  x.report("SQUARE_BRACKETED") {
    if markup =~ SQUARE_BRACKETED
      Regexp.last_match(1)
    end
  }
  x.report("start/end_with?") {
    if markup&.start_with?('[') && markup&.end_with?(']')
      markup[1..-2]
    end
  }

  x.compare!
end
```

## Result
```
Warming up --------------------------------------
    SQUARE_BRACKETED   261.300k i/100ms
     start/end_with?   548.813k i/100ms
Calculating -------------------------------------
    SQUARE_BRACKETED      2.632M (± 0.6%) i/s -     13.326M in   5.064085s
     start/end_with?      5.471M (± 0.5%) i/s -     27.441M in   5.015770s

Comparison:
     start/end_with?:  5470994.1 i/s
    SQUARE_BRACKETED:  2631642.3 i/s - 2.08x  (± 0.00) slower
