fix #5229: Add language configuration items for js, ts and jsx

[BroKun]

Signed-off-by: Brokun brokun0128@gmail.com

What it does

Added some configuration items that only exist in vscode, some may not be used yet.
There are still some differences, we can handle them when we upgrade the editor.

How to test

Type a multi-line comment, and the enter key will bring the right code.

@BroKun Just to check: now it is aligned with VS Code right? it is important to have the same, since in future we want to consume them directly from VS Code built-in extensions. Please provide links for copied code 🙏

The best would be if you file a CQ following this process: https://github.com/theia-ide/theia/wiki/Registering-CQs#codecontent-is-copied-from-other-projectsrepos If it is too involving please ping @theia-ide/ip-help for help.

Hi @BroKun, just wanted to know if you had any update on the PR, or if you needed help :)

[vince-fugnitto]

It works correctly for me, I now see block comments correctly:
Example:

/**
 * 
 * 
 */
const a = 10;

I understand the only thing left to do is register and wait for a CQ?

@vince-fugnitto the CQ has been approved, let's merge it.
