The implementation of the `CSV` shortcut method is broken in Ruby 3
for calls that look like this:
```ruby
CSV(write_stream, col_sep: "|", headers: headers, write_headers: true) do |csv|
...
end
```
The above will result in the following error when the `CSV` method attempts to pass
on arguments to `CSV#instance`:
```
ArgumentError: wrong number of arguments (given 2, expected 0..1)
```
The issue is due to the changes in Ruby 3 relating to positional & keyword arguments.
This commit updates the `CSV()` shortcut implementation to work with Ruby 3, and also
updates the documentation for the shortcut method.

This PR adds `undef: :replace` option for `CSV.open`.
`File.open` has `undef: :replace` option, but `CSV.open` does not.
It would be convenient if `CSV.open` could have a shortcut by having
`undef: :replace` option.
