feat: Respect `RateLimit` headers in default REST backoff implementation

[ReubenFrankel]

Feature scope

Taps (catalog, state, stream maps, tests, etc.)

Description

This IETF draft defines a series of RateLimit headers:

• X-RateLimit-Limit
• X-RateLimit-Remaining
• X-RateLimit-Reset

Taps built with the SDK around REST APIs that respond with these headers would benefit from a default RESTStream backoff implementation that understands and respects them - namely X-RateLimit-Reset.
