CLOUDP-298233: postman transformation in js

[wtrocki]

Proposed changes

CLOUDP-29823

With current bash based transformation it is hard to make any changes and effectively test them.
This PR introduces transformation engine in JS (as alternative to bash/regexp patterns).

Testing

I have tested input of both jobs and they produce exactly the same output.
Tests will be added in follow-up PR

Benefits

• Easier to make follow up changes and maintain the code.
• Unit tests possible
• Runtime on my machine changed from 61 seconds to 2 seconds.
• Removed couple immediate files/hacks

Follow up work/PRs

• Add tests
• Swap and Test CI/CD system to use JS targets.
• Add new postman transformations to introduce service accounts and document PAK enablement

Checklist

• I have signed the MongoDB CLA
• I have added tests that prove my fix is effective or that my feature works

Changes to Spectral

• I have read the README file for Spectral Updates

LGTM, one question on CJS vs ESM 👍

[lovisaberggren]

Q: Any reason to use commonJS instead of ESM?

[wtrocki]

ESM will require different setup (it did not work out of the box) so moved to cjs as it works out of the box with eslint. Will address this in follow up.
