[PROF-8289] Package libdatadog v5.0.0 for Ruby

**What does this PR do?**

This PR includes the changes documented in the "Releasing a new version
to rubygems.org" part of the README:
<https://github.com/datadog/libdatadog/tree/main/ruby#releasing-a-new-version-to-rubygemsorg>

(It's also exactly the same as
[the v4.0.0 release PR](#238)).

**Motivation:**

Enable Ruby to use libdatadog v5.0.0.

**Additional Notes:**

N/A

**How to test the change?**

I've tested this release locally against the changes in
DataDog/dd-trace-rb#3169 .

As a reminder, new libdatadog releases don't get automatically picked up
by dd-trace-rb, so the PR that bumps the Ruby profiler will also test this
release against all supported Ruby versions.
