fix VSCode API: run config reload with additional context providers

[ajshedivy]

Description

Fix for #3678

This pull request introduces changes to the configuration handling in the core/config module. The main improvements include adding support for additional context providers during the configuration reload process.

Key changes:

Configuration Handling Enhancements:

• core/config/ConfigHandler.ts: Modified the reloadConfig method to accept an array of IContextProvider as an optional parameter. This allows for additional context providers to be passed during the reload process.
• core/config/ConfigHandler.ts: Updated the registerCustomContextProvider method to pass the additionalContextProviders array when calling reloadConfig.
• core/config/ProfileLifecycleManager.ts: Updated the reloadConfig method to accept an array of IContextProvider as an optional parameter and pass it to the loadConfig method.

Nice catch, thanks for taking the time to fix this @ajshedivy !

Trying to figure out why the e2e tests are all failing here, think it is a permissions issue
