Remove unecessary dependency, updating dependency, and improving docs

[ikr4-m]

Here's what I made in this pull request:

1. Updating dependency because it has a bunch of vuln.
2. Removing copyfiles deps and set resolveJsonModule to make sure all of JSON file imported without using any deps aside from TypeScript
3. Make your docs have a little colors in examples.

Note (No. 2)

We can using this script to copy all JSON files from src to dist if resolveJsonModule is disabled:

#!/bin/sh

# Remove dist file
rm -rf ./dist

# Compile TypeScript to Javascript
tsc

# Find any file with .json extension in src and make some system execute using awk
find ./src/*/.json | awk '{system(print "cp " $1 " ./dist" substr($1, 6));}'

But I worry about developer that using Mac OS (GNU GAWK is totally different from BSD GAWK) so I just enabling resolveJsonModule and including all JSON files in tsconfig.
