Add incremental build by default in the generated tsconfig.json

[Convly]

What does it do?

Adds incremental builds by default for the generated tsconfig.json files.

Why is it needed?

Increase builds time and decreases used resources

How to test it?

1. Create a new TS project
2. Check that the incremental option is enabled in the generated tsconfig.json file
3. Make the first compilation, change a small line of code somewhere, and then rebuild. The second build should be faster than the first.
