[ruby-core:120363] [Ruby master Bug#20977] backtick is used for syntax errors related to 'it'

Issue #20977 has been reported by jnchito (Junichi Ito).

----------------------------------------
Bug #20977: backtick is used for syntax errors related to 'it'
https://bugs.ruby-lang.org/issues/20977

* Author: jnchito (Junichi Ito)
* Status: Open
* ruby -v: ruby 3.4.0rc1 (2024-12-12 master 29caae9991) +PRISM [arm64-darwin24]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
The following error message uses single quote for "'it'":

``` 
irb(main):012> [10].each_with_index { p "#{it}:#{_2}" } #=> 10
irb(main):013> 
<internal:kernel>:168:in 'Kernel#loop': (irb):12: syntax error found (SyntaxError)
> 12 | ... _2}" } #=> 10
     |     ^~ numbered parameters are not allowed when 'it' is already used
  13 | 
  14 | 
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/lib/ruby/gems/3.4.0+1/gems/irb-1.14.1/exe/irb:9:in '<top (required)>'
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/bin/irb:25:in 'Kernel#load'
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/bin/irb:25:in '<main>'

```

However, the error below uses backtick:

```
irb(main):019* [1, 2, 3].map.with_index(10) do |n, i|
irb(main):020*   it * i
irb(main):021> end
<internal:kernel>:168:in 'Kernel#loop': (irb):20: syntax error found (SyntaxError)
  19 | [1, 2, 3].map.with_index(10) do |n, i|
> 20 |   it * i
     |   ^~ `it` is not allowed when an ordinary parameter is defined
  21 | end
  22 | 
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/lib/ruby/gems/3.4.0+1/gems/irb-1.14.1/exe/irb:9:in '<top (required)>'
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/bin/irb:25:in 'Kernel#load'
	from /Users/jnito/.rbenv/versions/3.4.0-rc1/bin/irb:25:in '<main>'
```

So it should use single quote for consistency.
