Use Case

As a driver developer
I want our packages to compile with TS 6.x,
So that we can stay up-to-date with Typescript releases.

User Experience

• Each package owned by the node drivers team should be build cleanly on ES6, assuming no production code changes.

Dependencies

• None

Risks/Unknowns

• Given users consume our builds, there's a real chance that we build to a different module format or change the build output in a non-trivial way due to newly introduced features
• Multiple tsconfig files are used throughout our packages, and are used in different contexts. Each of these need to be smoke tested

Acceptance Criteria

Implementation Requirements

• Each repository which uses Typescript (mongodb-connection-string, mongodb-client-encryption, js-bson, node-mongodb-driver) should produce a bundle with near-parity to the original (exceptions allowed, assuming they're trivial and called out in the PR description)
• Each repository should pass existing tests which are run in CI which rely on typescript
• Existing tsconfig files should all be smoke tested 

Testing Requirements

• existing tests to be updated to support any changes which are a side-effect of ts6 update

Documentation Requirements

• Non-trivial diff's between main & the ts6 adoption branch (for each repo) should be justified and called out in each PR's description

Follow Up Requirements

• Packages which are blocked from updates should be noted as such
