Fix ambiguous Get() examples in README after new Params overload (#2486)

* Initial plan

* Add Get(path, params) overload to ClientImpl and Client; fix ambiguous test calls

* Fix clang-format style errors in test.cc

* Fix remaining ambiguous Get() calls in test_proxy.cc and test.cc

* Update README Get() examples to disambiguate Headers overload

 ```c++
 res = cli.Get("/resource/foo");
-res = cli.Get("/resource/foo", {{"Accept-Encoding", "br, gzip, deflate, zstd"}});
+res = cli.Get("/resource/foo", httplib::Headers{{"Accept-Encoding", "br, gzip, deflate, zstd"}});
 ```
 
 If we don't want a response without compression, we have to set `Accept-Encoding` to an empty string. This behavior is similar to curl.
 
 ```c++
-res = cli.Get("/resource/foo", {{"Accept-Encoding", ""}});
+res = cli.Get("/resource/foo", httplib::Headers{{"Accept-Encoding", ""}});
