Update http snippets for restsharp 107+

[llimllib]

a whack at fixing #312

To test this, I:

• generated all new fixtures with OVERWRITE_EVERYTHING=true npm run test
• generated a C# hello world project with dotnet new console -o HelloWorld -f net7.0
• installed RestSharp into it with dotnet add package RestSharp]
• ran this script and looked for significant differences between csharp and bash:

#!/usr/bin/env bashset -euxo pipefail
file=Program.cs
mkdir -p fixtures
# for the multipart testsprintf"hello"> hello.txt
forfixturein~/readme/kong-httpsnippet/src/targets/csharp/restsharp/fixtures/*;do
rm -f $file# the custom method isn't supportedif [[ $fixture==*custom-method* ]];thencontinue;fiprintf"using RestSharp;\n\n">$file
sed 's,test/fixtures/files/hello.txt,hello.txt,'"$fixture">>$fileprintf'Console.WriteLine("{0}", response.Content);'>>$file
dotnet run $file>"fixtures/$(basename "$fixture".out)"done## now run the bash fixtures for comparisonforfixturein~/readme/kong-httpsnippet/src/targets/shell/curl/fixtures/*;do# the curl for custom-indentation does not work properly, so we need to add# || true
sed 's,test/fixtures/files/hello.txt,hello.txt,'"$fixture"|
bash >"fixtures/$(basename "$fixture".out)"||truedone# then, compare the outputsforfixturein~/readme/kong-httpsnippet/kong-httpsnippet/src/targets/http/http1.1/fixtures/*;do
base=$(basename "$fixture")
cs="fixtures/$base.cs.out"
sh="fixtures/$base.sh.out"if [[ !-e$cs ]];thenprintf"Unable to find fixture %s\n""$cs";continue;fiif [[ !-e$cs ]];thenprintf"Unable to find fixture %s\n""$sh";continue;fi
git diff "fixtures/$base.cs.out""fixtures/$base.sh.out"||truedone
