chore: update dependencies and use send_non_blocking

[FlorentinDUBOIS]

• If you are using rustls instead of native tls version of this crate (through tokio-rustls-runtime or async-std-rustls-runtime), you HAVE TO call the CryptoProvider::install_default method once in your binary.

There is a warning about the deprecation of the send in doc tests

warning: use of deprecated method `pulsar::Producer::<Exe>::send`: instead use send_non_blocking
  --> src/lib.rs:78:14

48 |             .send(TestData {

Same for:

• src/producer.rs:166:23
• src/producer.rs:167:23
• src/producer.rs:402:19
• src/producer.rs:403:19

besides the doc test comment, seems good
