[Enhancement]: Switch the programming language of the currently opened problem file, but just in the editor.

[ClSlaid]

🚀 Feature Proposal

Offer a way to change the programming language, right the time in the editor, without opening the settings to change leetcode.defaultLanguage.

Motivation

In the online editor of leetcode, you can change the programming language you use freely. While using the plugin users have to open the settings to change the programming language.
