fix: `makeRequest` didn't add `url.query` to `u` when it is sending a GET request

fix CurlHttpClient.cpp

support boost-1.87.0

… current version of the tgbot-cpp library. This makes it challenging to handle successful payment events directly using the library.

Could you let me know if there are any plans to add this method in future updates? If yes, when can we expect it to be implemented?

Thank you for your work on this library, and I look forward to your response!

Best regards,

I noticed that the onSuccessfulPayment method is not available in the…

The `CurlHttpClient` currently produces an excessive number of
`connect()` syscalls, as every `makeRequest` creates a new TCP
connection. This inefficiency becomes particularly evident with
`TgLongPoll`, which continuously calls `getUpdates` in an endless loop,
creating a relentless cycle of `connect()` and `close()` operations.

A more sensible approach is to reuse HTTP connections by keeping them
alive across multiple requests. I suggest modifying the implementation
to allow the curl handle to persist until the `CurlHttpClient` object is
destroyed.

For thread safety, we can maintain a
`std::unordered_map<std::thread::id, CURL*> curlHandles` within the
`CurlHttpClient` class, ensuring each thread gets its own handle.

After all, treating connections like disposable napkins doesn't exactly
scream efficiency.

Added functionality to handle onSuccessfulPayment through Update with…
