chore: prepare next release

[otelbot-js]

Stable SDK (./CHANGELOG.md)

2.7.1

🐛 Bug Fixes

• fix(core, api): defer trace state validation. Deprecate trace state implementation in api #6459 @david-luna
  • important: this bug fix may be breaking for certain uses of TraceState
    • set now returns the same TraceState instance if key/value are invalid or makes the while trace state invalid.
    • unset now returns the same TraceState instance if key is not present.
    • best-effort parsing of invalid TraceStates has changed: when multiple keys with the same name are present, the most recent one will win.
