chore: npm audit fix

[boolafish]

Note

Got an dependency security alert from Github. Instead of just solving that, runs "npm audit fix" first and luckily the reported issue is covered as well. The reported dependency is minimist. It recommend to use version >= 1.2.2

• alert: https://github.com/omisego/plasma-contracts/network/alert/plasma_framework/package-lock.json/minimist/open

Test

It is set to ^1.2.5 after npm audit fix.
