Fix high severities

[xil222]

Fix 5 High Severities under following two issues:

1. https://npmjs.com/advisories/1550 --> "url-regex" all versions have this risk, the recommended way of changing requirement to "url-regex" to "url-regex-safe" wouldn't pass the test.
2. https://npmjs.com/advisories/1561 --> fix by installing node-forge version 0.10.0 and put that into package-lock.json
   By installing corresponding packages, and edit versions inside package-lock.json.

Since npm install won't install newest versions but just meeting criteria to requirement, running npm install again would change my manual definitions in package-lock.json.

If current solution isn't good enough, I'll try update version for packages on the root(to see if that could raise the requirement of versions for its dependencies)

The root package for node-forge is firebase-tools (not up-to-date)
The root package for url-regex is gulp-concat-css (has been up-to-date)

ps:
I updated firebase-tools to most recent version, somehow the node-forge installed still in version 0.9.2 which has high severities.

I reverted the manual changes in package-lock.json
