Subject: [PATCH] mediasoup-worker linux prebuilt with io-uring support (part
 1)

This PR exposes kernel mayor number in the mediasoup-worker binary name to make it possible to have prebuilts for Linux with kernel 5 and 6 (the latter supports `io-uring`).

**NOTE 1:** This is related to issue #1282 but doesn't complete it.

**TODO:** In `mediasoup-worker-prebuild.yaml` we must include an Ubuntu version with kernel >= 6. Problem is that Ubuntu 22.04 still uses kernel 5.15 and there are no other more modern Ubuntu versions in GitHub CI.

**NOTE 2:** When that is done (in part 2 of this task), we must still keep Ubuntu 20.04 since, as documented in the job file, it uses an older version of GLib and otherwise we'd run into this issue again: https://github.com/versatica/mediasoup/issues/1089.
