CURLOPT_NOPROXY not supported

[yami0101]

Hi. It seems that the CURLOPT_NOPROXY is missing in ext/curb_easy.c, which in turn gives a type error, when trying to set it:

irb(main):046:0> url = 'https://google.com'
irb(main):047:0> curl = Curl::Easy.new(url)
irb(main):049:0> curl.set(:noproxy, "")

.rbenv/versions/3.0.1/lib/ruby/gems/3.0.0/gems/curb-1.0.5/lib/curl/easy.rb:44:in `rescue in set': Curb doesn't support setting noproxy [#10177] option (TypeError)
.rbenv/versions/3.0.1/lib/ruby/gems/3.0.0/gems/curb-1.0.5/lib/curl/easy.rb:42:in `setopt': Curb unsupported option (TypeError)

This is needed to be able to override the no_proxy / NO_PORXY ENV var in some specific cases.

This option is already present in both ext/curb.c (line 509) and ext/extconf.rb (line 180). Would it be possible to add it to ext/curb_easy.c as well?

There were already similar issues closed #280

Thank you in advance.
