Refactor: simplify req.acceptsEncodings with spread syntax

[Ayoub-Mabrouk]

Replaced use of arguments in req.acceptsEncodings with the spread syntax (...encodings) to improve readability and reduce code complexity, while maintaining the same functionality.

Hello @Abdel-Monaam-Aouini Thanks for your input on this! I went with a slightly different approach to keep things concise by calling accepts(this).encodings(...encodings) directly, avoiding the intermediate accept variable. This makes the code a bit more streamlined and skips a minor, unnecessary allocation. I thought this might be more consistent with our style, but I’m happy to discuss if you see other benefits to your approach!
