Add "require 'uri'" for LSP

[pocke]

Steep langserver uses uri library but it isn't required.

$ git grep URI
lib/steep/drivers/watch.rb:              uri = URI.parse(response[:params][:uri])
lib/steep/server/code_worker.rb:            uri: URI.parse(project.absolute_path(path).to_s).tap {|uri| uri.scheme = "file"},
lib/steep/server/code_worker.rb:            paths = request[:params][:arguments].map {|arg| source_path(URI.parse(arg)) }
lib/steep/server/code_worker.rb:          path = source_path(URI.parse(request[:params][:textDocument][:uri]))
lib/steep/server/interaction_worker.rb:          uri = URI.parse(request[:params][:textDocument][:uri])
lib/steep/server/interaction_worker.rb:          uri = URI.parse(params[:textDocument][:uri])
lib/steep/server/master.rb:          uri = URI.parse(message[:params][:textDocument][:uri])
lib/steep/server/signature_worker.rb:        path = source_path(URI.parse(request[:params][:textDocument][:uri]))
lib/steep/server/signature_worker.rb:              uri: URI.parse(project.absolute_path(path).to_s).tap {|uri| uri.scheme = "file"},
lib/steep/server/utils.rb:        path = source_path(URI.parse(request[:params][:textDocument][:uri]))
test/code_worker_test.rb:        assert_equal Pathname("lib/success.rb"), project.relative_path(Pathname(URI.parse(uri).path))
test/code_worker_test.rb:        assert_equal Pathname("lib/annotation_syntax_error.rb"), project.relative_path(Pathname(URI.parse(uri).path))
test/code_worker_test.rb:        assert_equal Pathname("lib/ruby_syntax_error.rb"), project.relative_path(Pathname(URI.parse(uri).path))

So the langserver raises an error.

This pull request fixes this problem by adding a require.

@pocke Let me confirm. Did it cause a real problem? (I guess it shouldn't have caused any problem because it is loaded by rubygems.)

Yes, I guess the cause is ruby HEAD. I got the error with Ruby built with the master branch. Maybe the HEAD of rubygems removes URI dependency.

rubygems/bundler#7460 Rubygems starts to use vendored URI since this PR.

I got it! It totally makes sense. Thanks. 🙏
