Adding missing type definitions "inExperiment"

[nethan-freely]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

We're using the result of inExperiment from LDEvaluationReason so we're patching it locally as it's not in the type definitions
https://docs.launchdarkly.com/sdk/concepts/evaluation-reasons

Here is the diff that solved my problem:

diff --git a/node_modules/launchdarkly-js-sdk-common/typings.d.ts b/node_modules/launchdarkly-js-sdk-common/typings.d.ts
index a3bd0d5..5fbdabb 100644

Hello @nethan-freely,

Thank you for reaching out. We will be including this in the type definitions in a future version.

Thank you,
