[TS] Automatic closing bracket is missing, when inserting opening bracket

### Description

When I type "export class Test {" and hitting enter, the editor sets the cursor into the correct position but without adding an automatic closing bracket as for JS or other languages.

### Use case/motivation

For the first thing I would suggest to do the same as for JS and later on, we can add an option to hit { and it automatically adds a closing bracket as for ( in js. So this should work for normal, array diamond (in the right context) and block brackets.

Reproduce the issue in the TypeScript editor with `export class Test {` followed by Enter, then compare the result with JavaScript and other language editors. Trace the existing automatic bracket behavior and define done as adding the appropriate closing bracket for normal, array-diamond, and block-bracket contexts.
