Describe the bug

Got this error after upgrading from 6.1.3 to 6.4.3:

tsc -b tsconfig.build.json
Error: node_modules/unleash-client/lib/repository/index.d.ts(9,29): error TS7016: Could not find a declaration file for module 'launchdarkly-eventsource'. '/home/runner/work/(redacted)/node_modules/launchdarkly-eventsource/lib/eventsource.js' implicitly has an 'any' type.
Try npm i --save-dev @types/launchdarkly-eventsource if it exists or add a new declaration (.d.ts) file containing declare module 'launchdarkly-eventsource';

Shouldn't @types/launchdarkly-eventsource be listed as a dependency?

Steps to reproduce the bug

In a project using Typescript, upgrade from 6.1.3 to 6.4.3 (not sure when the dependency on launchdarkly-eventsource was introduced, maybe 6.3.0)
Try to compile.

Expected behavior

Should compile without issue

Logs, error output, etc.
