[ruby-core:121252] [Ruby master Bug#21174] Range#max called with an argument on a beginless Integer Range raises RangeError

      Issue #21174 has been reported by andrykonchin (Andrew Konchin).

Bug #21174: Range#max called with an argument on a beginless Integer Range raises RangeError
https://bugs.ruby-lang.org/issues/21174

* Author: andrykonchin (Andrew Konchin)
* Status: Open
* ruby -v: 3.4.2
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
It seems surprising but instead of returning last `n` Integers `Range#max(n)` raises `RangeError`:

```ruby
(nil..10).max(2)
# => (irb):3:in 'Range#max': cannot get the maximum of beginless range with custom comparison method (RangeError)

```

I would expect `[9, 10]` to be returned.
