rollbar vulnerable to prototype pollution

Description

Prototype pollution potential with the utility function rollbar/src/utility.set(). No impact when using the published public interface.

If application code directly imports set from rollbar/src/utility and then calls set with untrusted input in the second argument, it is vulnerable to prototype pollution.

Recommendation

Update the rollbar package to the latest compatible version. Followings are version details:

• Affected version(s): **>= 3.0.0-alpha1, <= 3.0.0-beta4

  <= 2.26.4**
