Migrate existing lock file parsers to new Dependency Scanning analyzer

Why are we doing this work

In order to iterate quickly, we'll be re-using as much as possible from the Gemnasium project. The quickest wins are existing lock file parsers for packagers like npm or pnpm.

Non-functional requirements

• Documentation: We should document the lock file support in the CI/CD component README.
• Feature flag:
• Performance: We should verify the performance on large lock files.
• Testing: We should ensure that the lock file parser tests continue to pass.

Implementation plan

Copy the following parsers along with their respective tests from the gemnasium project.

• bundle
• cargo
• cocoapods
• dot
• gemfile
• go Removed because of build removals.
• npm
• pipdeptree
• pnpm
• poetry
• swift
• yarn

Verification steps

1. Run go test ./... and ensure that all the tests pass
2. Verify that the CI/CD pipeline passes.
