wasabi dependency requirement is too relaxed for Ruby 3

[sarahsehr]

Bug report

Current behavior:

ruby/3.2.1/lib/ruby/gems/3.2.0/gems/wasabi-3.5.0/lib/wasabi/parser.rb:89:in `parse_url': undefined method `unescape' for URI:Module (NoMethodError)

      unescaped_url = URI.unescape(url.to_s)
                         ^^^^^^^^^

Steps to reproduce current behavior:

1. depend on savon
2. depend on version of wasabi v3.5.0
3. Run app console
4. Call Savon.client.call, for example:

Savon.client(wsdl: 'http://www.dneonline.com/calculator.asmx?WSDL').call(:add)

Expected behavior:

Savon requires that the minimum wasabi version is v3.7.

The cause of this Ruby 3 related error is removed in v3.6. However, wasabi was not tested against any version of Ruby 3 until v3.70.

System information:

• ruby version: 3.2.1
• savon version: tested against 2.11.2 and 2.13.0. Note savon v2.14.0 is okay because savon's httpi version requirement is incompatible with wasabi v3.5's httpi version requirement.

Additional Context

I'm filing this bug because it took me time to debug this when upgrading to Ruby 3. Hoping to save someone else the trouble.

Would you want to make a PR updating that requirement (which now says 3.4 or higher) to something which avoids defects?
