[Feat] Auto update vscode settings and .gitginore

[lollipopkit]

First of all, fvm is an awesome tool that has greatly improved my productivity.
Second, thanks for your code review.

auto config vsc settings and .gitignore

This change is to avoid the tediousness of manually adding settings.

Here are three points:

• use --config-vsc to update .vscode/settings.json:

• if without --config-vsc, it will ask for confirm:

• confirmation on setting auto merge:

add () to Y/n in console_utils.confirm()

This change allows users to quickly and accurately know what to type.

All code is formatted.
If you have any suggestion, I will revise it asap.
