This change enables the rustls-tls feature flag on the reqwest dependency. This allows it to use rustls in place of the openssl dependency, which should allow for further compatibility on different Linux distributions.

As far as I can tell, default-features must be disabled for this to work. From my testing, it doesn't seem to make a difference (i.e. cause an error) when it comes to building the project.

As it stands, the Linux binary for the latest release produces the following error on Ubuntu 22.04:
error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
I suspect this is because the version of Ubuntu the binary was compiled on is different, so it expects a different version of OpenSSL.

This can also be solved by including the openssl dependency with the vendored feature enabled, but it seems like most Rust projects are using rustls now (including rbxcloud and aftman).
