chore: prepare next release

[otelbot-js]

2.2.0

🐛 Bug Fixes

• fix(core): avoid leaking Node.js types via unrefTimer() util #5986
• fix(core): avoid leaking Node.js types via otperformance #5987 @pichlermarc
  • important: this bug fix may be breaking for certain uses of otperformnace
    • otperformance.now() and otperformance.timeOrigin are not affected.
    • the previously used type was incorrect and overly broad, leading to unexpected run-time behavior runtimes that are not Node.js.
    • these problems are now caught on compile-time: if you have been using this API and this change is breaking to you, please consider using your target platform's performance implementation instead.
