[🐛] yarn 2 lock file parsing issues

[regevbr]

• node -v: 12
• npm -v: yarn 2
• snyk -v: snyk/actions/node@master
• OS: linux
• Command run: snyk/actions/node@master

Expected behaviour

Work well with yarn 2 lock files

Actual behaviour

yarn.lock parsing failed with an error: Unknown token: { line: 3, col: 2, type: 'INVALID', value: undefined } 3:2 in lockfile

Steps to reproduce

create a project with yarn 2 and a github actions workflows that uses the snyk/actions/node@master action

Found issues

You use @yarnpkg/lockfile to parse the lock file, but it doesn't support yarn 2 lock files as they contain

__metadata:
  version: 4

which the parser does not support.

Suggested solution

realize that the repo is using yarn 2 (the existence of .yarnrc.yml is the indicator) and then use a different parser (I couldn't find an equivalent in yarn 2)
Removing the __metadata line manually still doesn't solve the issue, we need to use a different parser

[regevbr]

It seems that the "equivelnt" package for yarn 2 is @yarnpkg/parsers and the usage is:

const parsers = require('@yarnpkg/parsers');
parsers.parseSyml(file);

But it seems that the output is different than what you are expecting
