Description

This helps to fix #245 (comment)

By always using .ts files internally, we can ensure that types are checked in the same way that they would be by consumers

Steps to test

• No functional changes at all - you can verify this because the build doesn't produce any changes to the artifacts (in the first commit, the second has password rules updates)

[github-actions]

Note: Password rules outdated

auth.readymag.com not present in current
	rules: minlength: 8; maxlength: 128; required: lower; required: upper; allowed: special;

You can update the rules with the following command

cd packages/password && npm run rules:update

Once you've updated the rules, re-run the build from the root with npm run build and then commit all changes.
