Investigate/implement code uncommenting in CLI scrubber

[sherryhli]

Context

Currently, part of the work involved in merging new changes into the release branch from main is uncommenting certain code blocks, e.g. the AuthAPIClient, which contains both REST and GraphQL implementations but has REST commented out. Automatic uncommenting will streamline the release process (less work, less error prone).

Acceptance Criteria

• The scrubber should detect commented code blocks between a pair of "tagsToKeep" and uncomment them

Dev Notes

• Consider how we will handle nested tags
