The XGleanHeadersHook read the correct includeExperimental option and X_GLEAN_INCLUDE_EXPERIMENTAL env var but emitted the wrong header name. The backend expects X-Glean-Include-Experimental. Correct the header constant (and javadoc); the test consumes the constant so it is covered automatically.

Summary
The
XGleanHeadersHookBeforeRequesthook correctly reads theincludeExperimentalSDK option and theX_GLEAN_INCLUDE_EXPERIMENTALenv var, but sets the wrong header name. It emitsX-Glean-Experimentalwhen the backend expectsX-Glean-Include-Experimental.This corrects the
HEADER_EXPERIMENTALconstant (and javadoc). Behavior (opt-in, env var precedence) is unchanged. The test references the constant, so it's covered automatically.Changes

Same bug exists in the TypeScript, Go, and Python SDKs; companion PRs fix each. Env var name was already correct and is unchanged.
